Having looked at MCP, Models, and RAG, I realised that I’ve been mentally skirting around something that I don’t really understand, so I’m going to expose myself to some ridicule here and try to understand better: what’s the difference between AI and ML? Aren’t they just the same?
What’s the difference between AI and ML?
OK we’re doing this are we? __I thought AI was just ✨magic✨?_ And ML was the thing that got data scientists mad stacks ten years ago before everyone realised you couldn’t do shit without good data and processes?_
To me, a layperson in this space, watching it from the sidelines, AI and ML have been interchangeable. In fact, you’d get conferences and conference tracks titled "AI/ML"—because it’s all kind of the same thing anyway, right?
This is, of course, factually incorrect and presumably infuriating to anyone actually working in the field. The whole purpose of this blog series has been for me to at least reduce the number of unknown unknowns in my knowledge in this space—to build up a mental map of the different areas and terms so that I at least I know where to go and look when encountering something that I know I don’t know.
With that framing in mind, this is roughly how I understand the terms AI and ML:
Artificial Intelligence (AI) in its vernacular understanding in 2025 basically refers to using models (such as LLMs) that generate new output, often coupled with RAG and/or MCP, giving the semblance of "intelligence". So far as I’m concerned, this is the wrong definition to associate with AI , but it’s driven by something new that companies can use as a marketing angle.
Machine Learning (ML) is the discipline of training (and I use this as a broad term, to also include fine-tuning, reinforcement learning, etc) models using data. The models are what are then used in AI, through a process called inference.
My God…it’s full of marketing BS
Just like Cloud and Blockchain were previously, AI has become a lightning rod for every manner of ridiculous marketing claim and overinflated startup valuation.
Just like Cloud, at the heart of AI is a fundamentally new and important technological paradigm (JFC did I just write that un-ironically?), but at which it’s hard to get for the clamour of snake-oil salesmen around it promising the moon on a stick.
Just like Cloud, it’s a fool who dismisses AI as a fad.
Just like Cloud, it’s a reasonable person who wants to take a step back and understand what the all the fuss is actually about. And that’s what I’m trying my best to do in this series of blog posts.
