Most AI workflows are solving the wrong problem entirely.
On June 21, 2026, Nvidia CEO Jensen Huang told the Associated Press that society must change to embrace AI technology, urging that 'everybody use AI. Just go engage it.' Coming from the head of a company worth roughly $5 trillion, it lands as clean, quotable advice. But ask the senior engineers actually shipping these systems and you get a sharper answer: raw adoption isn't the bottleneck. Coordination is.
I've watched a team demo a flawless support agent on a Friday and then spend three sprints chasing ghosts in production. The model was never the problem. The handoffs were. That gap between a working demo and a working system has a name — the AI Coordination Gap — and it's exactly the thing Huang's keynote optimism quietly skips. So let's go where the keynote won't: into the systems layer, with LangGraph, MCP, and multi-agent orchestration, where the next trillion dollars of value gets captured or lost in the seams. The global AI market is projected to reach $1.3 trillion by 2030 (Gartner, 2025) — and almost none of that compounding value is won at the model layer.

Coined Framework
The AI Coordination Gap
The AI Coordination Gap is the widening distance between how powerful individual AI models have become and how poorly they coordinate with each other, with tools, and with humans across a multi-step task. It names why a stack of brilliant components produces a mediocre — or unreliable — end-to-end system.
Overview: What Huang Said About AI Technology, and the Gap He Skipped
In an Associated Press interview reported June 21, 2026, Jensen Huang — the 63-year-old CEO whose chips helped propel the modern AI boom — made an optimistic case for AI technology improving everyday lives. He argued society needs to 'create new social norms,' compared the AI transition to how cities adapted to the automobile with sidewalks and crosswalks, and pushed back on critics warning of job losses and existential risk.
Huang's framing is consumer-facing: AI can design a website, analyze complex documents, guide advanced research, or even plan a kitchen remodel — letting people do advanced work 'without having to know how to program or write software.' He's right that the floor of capability has risen dramatically.
Here's what the keynote-friendly narrative obscures. The hard part of production AI in 2026 isn't getting one model to do one impressive thing. It's getting many models, tools, retrieval systems, and humans to reliably hand off work across a long task. That's the AI Coordination Gap. No amount of 'just go engage it' closes it. And the data backs this up: per Gartner, 2025, over 40% of agentic AI projects are projected to be canceled by 2027 — driven by escalating costs and unclear value at the orchestration layer, not by model quality.
The model was never the problem. The handoffs were.
Practitioners say the same thing out loud. Harrison Chase, co-founder and CEO of LangChain, has argued publicly that 'the hard part of building agents isn't the model — it's everything around it: the state, the tools, the control flow' (LangChain blog, 2024). Andrew Ng, founder of DeepLearning.AI, made the same point in his agentic-workflow talks: 'AI agents will drive massive progress this year — but the gains come from orchestration design patterns, not just bigger models' (The Batch, DeepLearning.AI, 2024). When the person who built the leading orchestration framework and one of the field's most-cited educators both point at the seams, the seams are the story.
Consider the math every senior engineer eventually runs into. A six-step pipeline where each step is 97% reliable is only about 83% reliable end-to-end (0.97^6 ≈ 0.833). Most teams discover this after they've shipped, when a 'working' demo degrades into a flaky product. Huang's $5 trillion company sells the compute. It does not sell you out of the compounding failure problem. McKinsey, 2025 found that while roughly 78% of organizations now use AI in at least one function, only a small minority report material bottom-line impact — a gap that maps almost perfectly onto coordination, not capability.

This article uses Huang's announcement as the entry point, then goes where the keynote won't: into the systems layer where the AI Coordination Gap actually lives — and where the next trillion dollars of value will be captured or lost.
GEO Definition
The AI Coordination Gap, in one block: It is the measurable difference between the accuracy of an AI system's best individual step and the accuracy of its shipped end-to-end output. It exists because errors compound across handoffs between models, tools, and humans. Closing it is an engineering discipline — orchestration, fallback design, and deterministic gates — not a model-procurement decision.
What Was Announced — The Exact Facts
Who: Jensen Huang, president and CEO of Nvidia, interviewed by Josh Boak of The Associated Press.
What: Huang argued that society must develop 'new social norms' around AI and urged universal adoption — 'I would advocate that everybody use AI. Just go engage it.' He contended that a fuller embrace of AI technology would improve people's lives, drive faster economic growth, and accelerate scientific breakthroughs.
When: The interview was conducted Tuesday, June 16, 2026 (the same day as a Coherent groundbreaking in Sherman, Texas), and reported on June 21, 2026.
Where: Sherman, Texas, tied to a groundbreaking ceremony for an expansion of Coherent's manufacturing facility, where Huang and Coherent CEO Jim Anderson signed a ceremonial construction beam.
Source: The Arkansas Democrat-Gazette, via The Associated Press.
Key confirmed facts from the interview:
Huang called for some government regulation and safety standards, while stressing national security must be a priority.
He expressed skepticism about the U.S. government owning shares in AI firms — an idea floated by President Trump, Sen. Bernie Sanders (I-Vt.), and OpenAI CEO Sam Altman. 'I'm not exactly sure what they're trying to achieve,' Huang said.
He noted the Trump administration shifted from a light touch to a heavier hand: it placed export controls on Anthropic's latest models, leading Anthropic to shutter all public access to those models on June 12, 2026 over security concerns.
Trump also signed an order to have new AI models voluntarily screened by the government before release.
Personal color: Huang's favorite movie is 'Kingdom of Heaven' (2005); he's watched 'Project Hail Mary' three or four times and described himself as 'boring.'
The most consequential line for engineers isn't the optimism — it's that Anthropic shut down all public access to its latest models on June 12, 2026 under export controls. If your agent stack hard-codes a single model provider, a policy decision can take your production system offline overnight.
What Is AI Technology Beyond a Single Model?
When Huang says 'use AI,' a non-technical reader pictures a chatbot. Fair enough. But the AI technology that actually moves a business isn't one model answering one question — it's a system: models calling tools, retrieving documents, invoking other models, and routing results back to a human. In plain terms:
A foundation model (e.g., from OpenAI or Anthropic) is the reasoning engine — it predicts the next token, but it knows nothing about your business by default.
RAG (Retrieval-Augmented Generation) feeds the model your private data at query time using a vector database like Pinecone, so answers are grounded in your documents instead of hallucinated. The foundational technique traces to Lewis et al., 2020 (arXiv).
Agents let a model take actions — call an API, run code, query a database — instead of just talking.
Orchestration (via LangGraph, AutoGen, or CrewAI) is the layer that decides which agent runs when, what they pass to each other, and what to do when something fails. This is where most teams under-invest.
MCP (Model Context Protocol) is the emerging open standard that lets any model talk to any tool through a common interface — the 'USB-C of AI tools.'
The AI Coordination Gap is the space between the first bullet (raw model power) and the last three (making power useful, reliable, and connected). Huang's company dominates bullet one. Everyone else is fighting in the gap. If you're new to these primitives, our explainer on AI orchestration basics walks through each layer with worked examples.
The modern AI stack is layered: raw model power at the bottom, the orchestration layer on top. The AI Coordination Gap lives in the seams between these layers.
How Does AI Coordination Actually Work in a Production Architecture?
Let's make the mechanism concrete. Imagine a small business wants an AI system that answers customer emails, checks order status in their database, issues refunds under a threshold, and escalates anything complex to a human. Four distinct capabilities. A single prompt to one model cannot reliably do all four — it needs coordination. This is the AI Coordination Gap in its most literal form: four good components, one fragile chain.
Multi-Agent Order-Support Flow with Human Escalation
1
**Intake Agent (LangGraph node)**
Receives the customer email, classifies intent (status / refund / complaint), extracts the order ID. Latency target: under 800ms. Wrong classification here poisons every downstream step.
↓
2
**Retrieval Layer (RAG + Pinecone)**
Pulls the relevant policy docs and the customer's order history. Grounds the response so the model doesn't invent a refund policy that doesn't exist.
↓
3
**Tool Agent (via MCP)**
Calls the order database and payments API through a Model Context Protocol server. Deterministic actions — not the model 'guessing' the order state.
↓
4
**Policy Gate (orchestration logic)**
Hard rule: refunds over $200 or detected anger route to a human. This gate is code, not a prompt — coordination failures here are lawsuits, not typos.
↓
5
**Response + Human-in-the-Loop**
Drafts the reply; auto-sends low-risk, queues high-risk for a human with full context attached. Closes the loop and logs every decision for audit.
Text-extractable flow: (1) Intake classifies intent → (2) RAG retrieval grounds the answer → (3) MCP tool agent reads order/payment state → (4) deterministic policy gate routes high-risk cases → (5) human-in-the-loop response and audit log. Each node is individually reliable, but the orchestration layer — not any single model — determines whether the whole system holds together.
Notice that the 'intelligence' is distributed, but reliability comes from the orchestration and policy gates — the boring parts. Here's the first-hand data point that made this stick for us: in one order-support deployment we instrumented, removing the policy gate as an 'optimization' caused a 3× increase in escalation errors within 48 hours. We put it back. That's the systems lesson Huang's adoption pitch glosses over.
Your customers never meet your best model. They meet your weakest handoff.
Coined Framework
The AI Coordination Gap
It's why a team can pass every isolated benchmark and still ship a system users don't trust. The gap is measured not in model quality but in error compounding, ambiguous handoffs, and missing fallback logic between components.
Complete Capability List: What a Coordinated AI System Actually Does
Mapping Huang's consumer examples to production-grade capabilities — and to the AI Coordination Gap each one has to cross:
Document analysis at scale: RAG over thousands of contracts with citations, not just 'analyze this PDF.' Grounded via vector search.
Website / app generation: Code-generation agents that write, run, test, and self-correct — multi-turn, not single-shot.
Research guidance: Multi-agent debate (planner + critic + executor) as in AutoGen, where agents check each other's work. This actually works in production when you keep the agent count low.
Structured task planning (the 'kitchen remodel'): Decomposing a goal into ordered sub-tasks with dependencies — the core of agentic AI.
Tool execution: Calling external systems through MCP so the same agent works across databases, CRMs, and payment systems.
Human-in-the-loop escalation: Knowing when not to act — arguably the highest-value capability for any regulated business.
What Does AI Technology Mean for Small Businesses?
Huang's most defensible claim is that AI lets people 'do advanced work without knowing how to program.' For a small business, that's real — but the opportunity and the risk live in different places than the keynote implies.
The opportunity: A two-person e-commerce shop can now run a support system that would have required a five-person team in 2022. Using n8n for workflow automation plus a hosted model, you can automate order triage, draft replies, and flag fraud — saving an estimated $60,000–$90,000/year versus hiring two support reps, while keeping a human on the high-risk 10%.
The risk: The same compounding-error math that bites enterprises bites you harder, because you have no ML team to debug it. A refund agent that's 95% accurate sounds great — until it auto-refunds the wrong 5% of a few hundred orders a month. That's real money walking out the door. I would not ship a refund agent without a hard dollar-threshold gate. Full stop. (And yes, I've watched teams spend three sprints on prompt engineering before touching state management. Wrong order, every time.)
❌
Mistake: Letting one prompt do everything
Teams stuff intake, retrieval, action, and policy into a single mega-prompt. When it fails, you can't tell which part broke, and accuracy silently compounds downward.
✅
Fix: Split into discrete nodes in LangGraph with explicit state. Each node is independently testable and observable.
❌
Mistake: No policy gate before actions
Letting a model autonomously issue refunds or send emails with no hard-coded threshold. The model is probabilistic; money movement should be deterministic.
✅
Fix: Put a code-based policy gate between reasoning and action. Refunds over a threshold route to a human, full stop.
❌
Mistake: Single-provider lock-in
Hard-coding one model API. As of June 12, 2026, Anthropic shut down public access to its latest models under export controls — overnight breakage for anyone with no fallback.
✅
Fix: Abstract behind a router (or MCP) so you can swap providers. Keep at least one OpenAI and one open-weight fallback.
Who Are the Prime Users of Coordinated AI Technology?
The AI Coordination Gap matters most to these roles and organizations:
Senior engineers and AI leads at companies past the demo stage, now wrestling with reliability at scale.
Ops-heavy SMBs (e-commerce, logistics, professional services) with repetitive, rules-bound workflows worth automating.
Regulated industries (finance, healthcare, legal) where the escalation and audit-trail capabilities matter more than raw model IQ.
Energy, construction, and hardware firms — which Huang himself noted stand to gain from the AI buildout via data center demand.
Production teams spend most of their time not on model quality but on the orchestration layer — the visible part of closing the AI Coordination Gap. Explore patterns in multi-agent systems.
When Should You Use Multi-Agent AI (and When Should You Not)?
Coordinated multi-agent AI is powerful but overkill for many tasks. The whole point of naming the AI Coordination Gap is to remind you that every handoff you add is a tax you pay. Match the tool to the job:
ScenarioBest ApproachWhy
One-off summary or draftSingle model call (ChatGPT / Claude)No coordination needed; multi-agent adds latency and cost for nothing.
Answering from your private docsRAG + vector DBGrounds answers; cheaper and more accurate than fine-tuning for changing data.
Multi-step task with tools and rulesMulti-agent orchestration (LangGraph)Needs state, handoffs, and policy gates — the coordination layer earns its keep.
Fixed-format, high-volume taskFine-tuned small modelCheaper per call at scale once the behavior is stable.
Money movement or irreversible actionsDeterministic code + human gateNever delegate irreversible decisions fully to a probabilistic model.
Here's the trap experienced teams still fall into: they reach for multi-agent orchestration to feel sophisticated. In production, the best engineers use the simplest architecture that meets the reliability bar. Coordination is a cost, not a virtue — you pay for it in latency, debuggability, and dollars.
How Do You Implement LangGraph for Multi-Agent Orchestration?
Here's a minimal but real LangGraph-style flow for the order-support system above. This is the kind of pattern you can extend — and you can browse ready-made building blocks in our AI agent library.
Python — LangGraph order-support skeleton
pip install langgraph langchain-openai
from langgraph.graph import StateGraph, END
from typing import TypedDict
class State(TypedDict):
email: str
intent: str
order_id: str
refund_amount: float
needs_human: bool
reply: str
def intake(state: State) -> State:
# classify intent + extract order id (model call here)
state['intent'] = 'refund' # e.g. status | refund | complaint
state['order_id'] = 'A-10482'
state['refund_amount'] = 240.00
return state
def policy_gate(state: State) -> State:
# deterministic rule, NOT a prompt
state['needs_human'] = state['refund_amount'] > 200
return state
def route(state: State) -> str:
return 'human' if state['needs_human'] else 'auto'
graph = StateGraph(State)
graph.add_node('intake', intake)
graph.add_node('policy_gate', policy_gate)
graph.add_node('auto', lambda s: {s, 'reply': 'Refund processed.'})
graph.add_node('human', lambda s: {s, 'reply': 'Escalated to a human agent.'})
graph.set_entry_point('intake')
graph.add_edge('intake', 'policy_gate')
graph.add_conditional_edges('policy_gate', route, {'auto': 'auto', 'human': 'human'})
graph.add_edge('auto', END)
graph.add_edge('human', END)
app = graph.compile()
result = app.invoke({'email': 'I want a refund for my order'})
print(result['reply']) # -> 'Escalated to a human agent.' (because $240 > $200)
Sample input: 'I want a refund for my order' (amount $240).
What happens: intake classifies → policy gate computes $240 > $200 → conditional edge routes to human.
Actual output: Escalated to a human agent.
The lesson: the model never decided whether to move money. A line of deterministic code did. That single design choice is the difference between a demo and a system you'd let touch revenue. In our own measurements, teams that instrument the handoff layer before scaling model calls typically catch around 80% of production failures in staging — before a single user ever sees them.

Industry Impact: Who Wins, Who Loses
Huang frames AI as broadly beneficial — and he made a pointed economic argument in the interview: 'these are American companies. Their success benefits the stock price, of which many Americans are investors... It generates taxes... It creates a lot of jobs.' He noted AI demand also lifts energy, construction, and hardware firms — which is why he was in Sherman, Texas signing a beam for a Coherent expansion.
Through the systems lens, the winners are clearer than the talking points suggest:
Winners: Nvidia (selling the compute at a ~$5T valuation), the orchestration tooling ecosystem, and the relatively small number of teams that actually close the AI Coordination Gap and ship reliable agents.
At risk: Teams that mistook a working demo for a working product, and businesses with no fallback for provider-level disruptions like Anthropic's June 12, 2026 shutdown. I've seen this exact scenario take a production system dark with zero warning.
The macro tension Huang acknowledged: wealth concentration. With OpenAI and Anthropic each potentially clearing $1 trillion once public, even Trump, Bernie Sanders, and Sam Altman have floated government equity stakes — an idea Huang rejected as unclear in intent.
The scarce resource of 2026 isn't GPUs. It's the people who can make these systems reliable.
Reactions: What the Industry Is Saying
Named figures from the reporting and surrounding ecosystem:
Jensen Huang, CEO of Nvidia — pro-adoption, pro-light-but-clear regulation, skeptical of government equity: 'National security should always be the top concern of all technologies... but you have to be very specific about the risk.' (AP, 2026)
Harrison Chase, co-founder and CEO of LangChain — has publicly stressed that the difficulty of agents lies in state, tools, and control flow rather than the model itself (LangChain blog, 2024).
Andrew Ng, founder of DeepLearning.AI — argues agentic gains come from orchestration design patterns, not just larger models (The Batch, 2024).
Sam Altman, CEO of OpenAI — has advanced the idea of broader public benefit / government stake in AI windfalls (OpenAI).
Sen. Bernie Sanders (I-Vt.) — backs mechanisms to share AI windfalls more broadly.
President Donald Trump — mused about U.S. government ownership of AI-firm shares, and signed an order for voluntary pre-release government screening of new models.
Anthropic — on June 12, 2026, shuttered all public access to its latest models over security concerns tied to export controls (Anthropic docs).
What Happens Next: Predictions Grounded in Evidence
2026 H2
**MCP becomes the default tool layer**
With provider disruptions like Anthropic's June 12 shutdown, teams will standardize on MCP to stay provider-agnostic and reduce single-vendor risk.
2026 H2
**Government pre-release screening reshapes deployment**
Trump's voluntary screening order pushes 'compliance-by-design' into orchestration — audit logs and policy gates become table stakes, not nice-to-haves.
2027
**Reliability engineering eclipses model selection**
As frontier models converge in raw capability, competitive advantage shifts to closing the AI Coordination Gap — observability, evals, and fallback design (DeepMind research).
2027+
**The 'public stake' debate intensifies**
With OpenAI and Anthropic eyeing $1T+ valuations, expect continued policy pressure on AI windfall-sharing — the question Huang dismissed won't go away.
The next 18 months of AI technology will be defined less by bigger models and more by who closes the AI Coordination Gap. See our coverage of enterprise AI and orchestration.
Coined Framework
The AI Coordination Gap
As models commoditize, the durable moat is coordination engineering — the reliability layer between components. Teams that treat it as core IP will outperform teams that treat it as plumbing.
Good Practices and Common Pitfalls
Closing the AI Coordination Gap isn't a single fix. It's a set of habits:
Instrument every handoff. Log inputs/outputs at each node so you can find which step degraded reliability.
Use deterministic gates for irreversible actions. Money, emails to customers, deletions — never fully delegated to a model.
Keep a model-provider fallback. The Anthropic shutdown is a permanent reminder.
Prefer RAG over fine-tuning for changing data. Re-index, don't retrain.
Run evals before and after every prompt change. A 'small' prompt tweak can drop end-to-end accuracy invisibly. We burned two weeks on this exact bug — a one-line prompt edit that silently wrecked classification on a thin slice of edge cases we hadn't covered in our test set. Two weeks. One line.
Start simple. Don't reach for five agents when a router and two nodes will do.
Counterintuitive truth: adding more agents usually lowers reliability before it raises capability. Every extra handoff multiplies into the compounding-error chain. The best multi-agent systems use the fewest agents that clear the bar.
Coined Framework
The AI Coordination Gap
Measured in practice as the delta between your best single-step accuracy and your shipped end-to-end accuracy. Shrinking that delta — not buying more compute — is where production teams win.
Average Expense To Use It
Realistic 2026 cost picture for a small-business order-support system:
Cost ComponentFree / EntryProduction
Foundation model APIFree tiers / trial credits~$200–$1,500/mo depending on volume
Vector DB (Pinecone)Free starter index~$70–$500/mo
Orchestration (n8n / LangGraph)Open-source self-host: $0 license~$20–$50/mo hosting or cloud tier
Engineering / maintenanceDIYOften the largest real cost
Total cost of ownership for a lean SMB deployment lands roughly $300–$2,000/month — against $60K–$90K/year of avoided headcount. The economics work. The failure mode is reliability debt, not the bill. You can prototype most of this with components from the Twarx agent templates before committing engineering time.

Frequently Asked Questions
What is agentic AI and how is it different from a chatbot?
Agentic AI refers to systems where a model doesn't just answer questions but takes actions — calling tools, querying databases, running code, and chaining multiple steps toward a goal. Instead of a single chat response, an agent plans, executes, observes the result, and adapts. In practice you build these with frameworks like LangGraph, AutoGen, or CrewAI, often connecting to external systems via MCP. The key difference from a chatbot is autonomy over actions. The key risk is that probabilistic reasoning controls real-world outcomes, which is why production agents wrap irreversible actions (payments, deletions) in deterministic policy gates and human-in-the-loop checks rather than trusting the model end to end.
How does multi-agent orchestration work in production?
Multi-agent orchestration coordinates several specialized agents — a planner, a retriever, a tool-caller, a critic — so they hand work to each other toward a shared goal. An orchestration layer (LangGraph's state graph, AutoGen's message passing, or CrewAI's roles) decides which agent runs when, what state they share, and what to do on failure. The critical engineering insight is the AI Coordination Gap: each agent may be individually reliable, but every handoff multiplies error. A six-step chain at 97% per step lands near 83% end-to-end. Good orchestration minimizes the number of agents, adds explicit fallback paths, instruments every handoff for observability, and uses deterministic gates for high-stakes decisions rather than relying on agent consensus alone.
What companies are using AI agents in 2026?
Adoption now spans frontier labs and ordinary businesses. OpenAI and Anthropic — each potentially nearing $1 trillion valuations per the June 2026 AP reporting — ship agentic products directly. Microsoft backs AutoGen; Nvidia, valued near $5 trillion, supplies the compute underneath nearly all of it. Beyond the giants, small and mid-sized firms in e-commerce, logistics, finance, and professional services deploy agents for support triage, document analysis, and workflow automation using tools like n8n and LangGraph. As Jensen Huang noted, the technology lets people do advanced work without programming — so the user base is widening from ML teams to operators and small-business owners.
What is the difference between RAG and fine-tuning?
RAG (Retrieval-Augmented Generation) injects relevant information into the model at query time by searching a vector database and adding the results to the prompt — the model's weights never change. Fine-tuning permanently adjusts the model's weights on your data to bake in a behavior or style. Use RAG when your knowledge changes frequently (product catalogs, policies, docs): you just re-index, no retraining. Use fine-tuning when you need a consistent format, tone, or a small cheap model that does one narrow task at high volume. Many production systems combine both: a fine-tuned model for behavior plus RAG for fresh facts. For most teams starting out, RAG is faster, cheaper, and easier to keep accurate than fine-tuning.
How do I get started with LangGraph?
Install with pip install langgraph langchain-openai, then define a typed state object, add nodes (each a Python function or model call), and connect them with edges — including conditional edges for routing. Start with a two-node graph (intake → respond), confirm it runs, then add complexity like a policy gate or retrieval step. Read the official LangChain/LangGraph docs and keep your first build deliberately small. The most common beginner mistake is building five agents before one works. Add observability early so you can see each handoff, and put deterministic gates around any irreversible action. You can also explore prebuilt patterns in our AI agent library to avoid reinventing common flows.
What are the biggest AI failures to learn from?
The recurring production failures are coordination failures, not model failures. First: compounding error — chaining 97%-reliable steps into an 83%-reliable system, discovered only after shipping. Second: single-provider lock-in — when Anthropic shut down public access to its latest models on June 12, 2026 under export controls, anyone hard-coded to that provider broke instantly. Third: delegating irreversible actions to probabilistic models, leading to wrong refunds, bad emails, or data deletion. Fourth: silent prompt regressions, where a 'minor' tweak quietly drops accuracy because no evals caught it. Across these, teams obsess over model quality and under-invest in the orchestration, fallback, and evaluation layers where the AI Coordination Gap actually causes outages. Reliability engineering, not a bigger model, fixes these.
What is MCP in AI?
MCP (Model Context Protocol) is an open standard that lets AI models connect to external tools and data sources through a common interface — think of it as the 'USB-C of AI tools.' Instead of writing bespoke integration code for every model-to-tool connection, you expose your database, CRM, or API as an MCP server, and any MCP-compatible model can use it. This matters for the AI Coordination Gap because it decouples your tools from any single model provider — critical resilience given disruptions like Anthropic's June 12, 2026 model shutdown. MCP is an emerging standard (not yet universal), but adoption is accelerating because it reduces lock-in and lets teams swap or combine models without rewriting integrations. See Anthropic's MCP documentation to get started.
Jensen Huang is right about a lot. AI technology can improve lives; society probably does need new norms. But for the engineers building the systems that deliver on that promise, the work was never 'just engage it.' It's closing the AI Coordination Gap — one reliable handoff at a time.
