This article was written by Educative's Co-founder and CEO, Fahim ul Haq.

Just as cloud computing transformed businesses and industries when it first appeared in the mid-2000s, machine learning and artificial intelligence are poised to do the same right now. In fact, if it wasn't already clear — the AI revolution is fully upon us. We've seen the impact on companies that didn't adopt cloud technologies where it was needed quickly enough: they ended up losing market share to more agile competitors.

“Companies rarely die from moving too fast, and they frequently die from moving too slowly.”

So how will the AI revolution affect the tech industry and its hiring practices?

OpenAI's latest iteration of their large language model, GPT-4, has generated an abundance of hype and has sent the tech industry into a frenzy to adopt this new technology.

The latest advancements in AI have sparked a flurry of activity across multiple industries: marketing, finance, retail, education, and even healthcare. AI is in everything from customer service chatbots that can answer inquiries to automated processes to analytics that can be used to provide valuable data insights.

We're seeing widespread changes being made to integrate AI into key parts of business operations (whether necessary or not), and it's no surprise why. The possibilities seem endless when it comes to discovering what machine learning and artificial intelligence can do to make our lives easier.

Unfortunately, we're also seeing plenty of news articles that fail to convey the true potential of AI technology in favor of highly clickable depictions of AI lingering ominously on the verge of quasi-sentience. To help separate fact from fiction, we will look at what AI is, what it's being used to accomplish, and how you can leverage it to your advantage.

Let's dive right in!

Breaking down the GPT-4 hype

Only a few months after stopping the internet in its tracks with the debut of ChatGPT-3, OpenAI made waves once again on March 14th, 2023 when it unveiled its newest release: GPT-4.

GPT-4 is an advanced large language model developed by OpenAI and built on the GPT-4 deep learning architecture. GPT-4 is estimated to have about ten times as many parameters as GPT-3.5. OpenAI's previous language model, GPT-3, was trained on approximately 175 billion parameters.

Parameters, in the context of deep learning models such as GPT-4, refer to the biases in a model's neural network architecture that are learned during the training process. Parameters help the model identify patterns, relationships, and other features from the training data.
​​
In other words, the more parameters, the better.

Despite its capabilities, GPT-4 has its limitations. AI models can only learn and make decisions based on the parameters they're trained with, so it's not uncommon for chatbots built on these deep learning architectures to occasionally generate false or nonsensical responses. Like any other AI model, GPT-4 is still susceptible to unreliability, hallucinations, and biases.

How much better is GPT-4?

• Performance: GPT-4 outperforms existing large language models and most state-of-the-art models on traditional benchmarks. GPT-4 has demonstrated human-level performance on various professional and academic benchmarks, including scoring in the top 10% on a simulated bar exam.

• Reliability: GPT-4 is more reliable than GPT-3.5 and can handle more nuanced instructions while generating better responses.

• Steerability: GPT-4's steerability has improved, allowing developers to customize AI behavior using system messages. Steerability refers to the ability to guide or control the behavior of an AI system, particularly in generating responses or completing tasks according to specific user requirements.

• Safety: OpenAI spent 6 months aligning GPT-4 to improve factuality, steerability, and adherence to guardrails compared to GPT-3.5.

Impact of ML/AI on the tech industry

ML and AI technology are already starting to have a widespread and transformative impact on the tech industry. OpenAI’s work with GPT is just a small slice of this revolution.

As new products and technologies continue to emerge, we'll see improvements in other areas of business as well:

• Automation, optimization, and efficiency.
  ML and AI will likely have the most significant impact in these areas. More tasks will be automated to improve efficiency and productivity, increasing demand for AI-powered tools.

• Enhanced user experiences.
  As AI models become more sophisticated, they can handle more nuanced input, understand user preferences, and help provide personalized content and services.

• Data-driven decision-making. AI and ML are already being used extensively to harness the power of big data. Still, we can expect to see more accurate and reliable results that help drive better data-driven business decisions.

• New products and services. Improvements in ML and AI technology will inevitably lead to the development of products and services previously impossible to offer.

Hiring and Job Outlook for ML/AI

The career outlook for ML and AI specialists is exceptionally positive.

We expect to see an increased demand for ML and AI specialists as the technology improves. Because ML/AI technology is so data-intensive, we can also expect to see a similar increase in the demand for data scientists and other data professionals.

Furthermore, because ML/AI is ideal for handling mundane, logic-based tasks, we'll likely see more of a focus on hiring for creative, higher-level skills.

According to the US Bureau of Labor Statistics, careers in these fields are expected to grow by 21% from 2021-2031, with the median salaries for these roles sitting at an impressive $131K per year.
