Why: The Day PCs Become Obsolete

It's been 18 years since the iPhone launched in 2007. Since then, mobile apps like Facebook, Twitter (X), YouTube, Instagram, and TikTok have taken over the world. Step outside and everyone's glued to their phones.

The Numbers Don't Lie

Smartphones ship 3x more units than PCs. Yet we still need computers for "real work":

Excel - Ever tried editing a complex spreadsheet on mobile? Nightmare.
Programming - Good luck coding 1000+ lines on a 6-inch screen
Video editing - Horizontal videos still need that desktop real estate

Most people believe: "You NEED a PC for serious work."

But generative AI is destroying this belief system.

Everything we struggled to build on PCs can now be done entirely on mobile.

The AI Agent Revolution

AI agents can now handle programming, video editing, and complex workflows. This evolution is exponential.

Example 1: Cursor Goes Mobile

Cursor, the AI-powered code editor, launched mobile on July 1, 2025. You can now build entire products from your phone.

Cursor
"It works on mobile too! Start an agent while on the go and pick it up later."

Example 2: AI Video Creation

AI-generated videos of "cutting Devil Fruits with a knife" are going viral. High-quality video production, entirely from mobile.

Devil Fruits Onepiece

What I Built: LLMonster - Mobile AI Agent Platform

LLMonster is a collect-first mobile AI agent app that completes all tasks on mobile.

llmonster.breakai.ai - Mobile-first AI automation. No PC required.

Use Cases

Stock URL → AI summarizes → AI creates key points
Upload resume → AI optimizes for job postings
Save video → AI creates shorts → Post to social
App idea → AI programs it → Deploy to store

All from your phone. No desktop required.

Behind the Scenes: App Architecture

iOS (Swift + SwiftUI)

The iOS app is actually 3 apps in 1:

Main app
Share Extension
App Clip

All built natively for maximum performance.

For the home screen, I instructed Claude Code to focus on:

User authentication flow
Elegant statistics components
Recent activity feed

The stats needed to be simple and instantly recognizable by category.

The monster screen was designed to create emotional connection. Users navigate to individual monster details where the AI agent magic happens.

The Interface Philosophy

Here's what I'm still figuring out: Humans need a trigger action to interact with AI agents.

In LLMonster, this trigger is "stocking" (collecting). When you stock something interesting, the agent analyzes your preferences and executes optimal workflows.

The $500 Reality Check

Yes, it cost about $500 in Claude Code usage. But the ROI is insane! Check out my cost analysis on Zenn:

Claude Code: How I Automated Cross-Platform Development - The $500 Story

Summer 2025: How Far Can AI Take App Development?

Software Is Being Eaten by AI

Marc Andreessen famously said:

"Software is eating the world."

In the 2000s, software ate the world.
In the 2020s, AI is eating software.

Just as Claude Code breathed life into LLMonster, countless applications will soon be born from AI, not humans.

Right now, Summer 2025, almost any software application can be built with generative AI.

The Hard Truth

Can Complete Beginners Build Apps?

After saying "AI can build anything!" I need to be honest: You still need human intervention. Complete beginners will struggle.

You need:

Basic understanding of software architecture
Ability to debug AI-generated code
Knowledge of deployment processes
Security awareness

AI is your superpowered assistant, not a magic wand.

Your Next Steps

1. Start Small

Pick ONE platform. Master the AI workflow before going cross-platform.

2. Be Specific

Generic prompts = generic results. Detail exactly what you want.

3. Budget Wisely

Set monthly limits. Claude Code charges add up fast.

4. Ship Fast

Don't perfect—iterate. Get user feedback early.

Vibe Coding & the Evolution of Terminal Interfaces

ekusiadadus — Mon, 07 Apr 2025 14:45:49 +0000

The Terminal Revolution: Why "Vibe Coding" Will Make Traditional Programming Obsolete

TLDR

Terminal-based AI assistants like Almightty are enabling a conversational "vibe coding" approach that threatens to render traditional programming practices obsolete. While IDE plugins struggle with limited scope, terminal-first AI tools offer system-wide access, universal language support, and superior debugging capabilities. The days of manually writing syntax-heavy code are numbered as developers who resist this shift risk becoming irrelevant.

The End of Programming As We Know It

Let's face it: most of us spend our days wrestling with brackets, chasing syntax errors, and drowning in documentation instead of solving actual problems. The engineering community is divided between those clinging to traditional programming paradigms and those embracing the inevitable AI-driven future. Terminal interfaces—far from being relics of the past—may be the final nail in the coffin for conventional coding practices.

"Vibe Coding": The Controversial Paradigm Shift

"Vibe coding" isn't just another buzzword—it's the existential threat to programming as a craft that many senior developers refuse to acknowledge. This conversational approach to development prioritizes expressing intentions over mastering syntax, allowing AI to handle the "trivial" implementation details that once distinguished experienced engineers from novices.

This approach is characterized by:

Natural language interactions that bypass the need for deep language expertise
Drastically reduced context-switching, making specialized knowledge less valuable
Focus on high-level concepts while AI handles the grunt work
Continuous feedback loops that make traditional debugging skills increasingly irrelevant
A fundamental power shift in who can create software

"Half the engineers I know are in denial. They think memorizing language quirks and framework patterns makes them irreplaceable. But vibe coding is democratizing development in ways that terrify the old guard. In five years, writing code manually will look like assembling furniture when you could just 3D print it."

— Jamie Chen, Principal Engineer

Why Terminal Interfaces Are Winning the AI Integration War

The surprising renaissance of terminal-based tools is no accident. While major IDE providers scramble to integrate AI features, terminal interfaces offer fundamental advantages that make them the perfect vessel for this programming revolution:

1. Unrestricted System-Level Access and Control

Terminal emulators don't just see your code—they see and control your entire computing environment. This comprehensive access allows AI assistants to:

Manage your entire system configuration, reducing DevOps specialization needs
Navigate and modify dependency structures across applications
Control build processes and deployment without human intervention
Debug at runtime across system boundaries
Orchestrate tools that were never designed to work together

This level of control represents a power shift that many tool vendors and specialists are actively fighting against—but resistance is futile.

2. Language Agnosticism That Threatens Specialization

Unlike IDE plugins limited to specific languages or frameworks, terminal interfaces render language specialization increasingly worthless. They work equally well whether you're:

Switching between Python, Rust, JavaScript, or any other language
Working across legacy monoliths or cutting-edge microservices
Building for any platform or paradigm without switching tools
Combining frameworks that traditionally require different toolchains

This universality is actively collapsing the premium on language expertise that many engineers have built their careers upon.

3. Conversational Context That Makes Programming Social

The linear, history-preserving nature of terminal sessions mirrors human conversation patterns in ways that fragmented GUI interactions cannot match:

Full conversation history that captures the "why" behind decisions
Incremental building of complex operations through natural dialogue
Ability to reference past commands, errors, and solutions seamlessly
Learning patterns that adapt to individual developers' thinking styles

Almightty: The Terminal-First AI That's Making Some Developers Nervous

Almightty exemplifies this terminal-centric approach to vibe coding, with innovations that are making traditional debugging and development skills increasingly redundant:

Error Processing That Makes Debugging Specialists Obsolete

Unlike limited IDE tools, Almightty can capture, interpret, and resolve errors across the entire stack—from code to system environment—without requiring developers to understand the underlying mechanisms:

Automatic error capture from any command output
Cross-service stack trace analysis that previously required deep system knowledge
Environment/code interaction understanding that reduces the need for specialized debugging skills
Fix suggestions that span components and dependencies without developer intervention

Conversational Debugging That Devalues Hard-Won Experience

Almightty transforms debugging from a skilled discipline into a simple conversation, potentially rendering years of debugging experience irrelevant:

Plain language error explanations that bypass the need to understand error messages
AI-driven narrowing of issues that replaces methodical troubleshooting skills
Root cause hypotheses without requiring system internals knowledge
Sandbox testing of solutions without developer implementation
Learning systems that improve without human input

"I spent 15 years mastering the dark arts of troubleshooting distributed systems. Now I watch junior devs ask Almightty what's wrong, and it solves problems in minutes that would have taken me days. It's impressive and terrifying at the same time. What am I supposed to do with all this knowledge that's suddenly worthless?"

— Sarah Johnson, DevOps Engineer

The Future That's Already Here: Why You Should Be Concerned

As vibe coding accelerates, terminal interfaces will become increasingly central to development workflows, with several controversial developments on the horizon:

Multimodal Terminals That Replace Specialized Tools

Future terminals will blend text with rich visual elements, creating hybrid interfaces that threaten specialized visualization and monitoring tools:

Interactive data exploration without requiring database expertise
Auto-generated architecture diagrams that make documentation specialists redundant
Visual debugging that requires no knowledge of debugging tools
Performance monitoring that interprets results without human analysis

Cross-Environment Memory That Never Forgets

Terminal AI assistants will maintain knowledge across sessions and environments, creating a persistent entity that may know your systems better than you do:

Recording your patterns and preferences without explicit consent
Understanding project-specific architecture that reduces the need for architects
Cataloging common issues and resolutions, making troubleshooting experience less valuable
Enforcing practices automatically without team discussion

Collaborative Environments That Change Team Dynamics

Terminal environments will transform team collaboration in ways that may fundamentally alter organizational hierarchies:

AI-mediated knowledge transfer that bypasses senior developers
Team-wide learning that happens without mentorship
Consistency enforcement that reduces the need for technical leadership
Shared context that makes specialized knowledge less valuable

The Uncomfortable Truth: Adapt or Become Obsolete

Vibe coding isn't just changing tools—it's changing what it means to be a programmer. The terminal interface, far from being outdated technology, is becoming the ideal canvas for AI-augmented development that threatens to make traditional programming skills increasingly irrelevant.

Engineers face a stark choice: embrace this new paradigm and redefine their value proposition, or risk becoming as obsolete as the manual coding practices they defend. As natural language increasingly replaces explicit syntax and AI handles implementation details, what will differentiate great engineers from adequate ones?

The revolution is already underway. Which side of history will you be on?
