Artificial Intelligence. Two words that generate more opinion than almost any other topic online right now. But what is it actually?
The simple version
At its core, AI is software that has been trained to recognise patterns — in language, images, data, sound — and respond to them in ways that appear intelligent. It doesn’t think the way humans think. It doesn’t have opinions, feelings or ambitions. What it does have is the ability to process vast amounts of information and produce useful outputs based on what it has learned.
When you type a question into an AI assistant and receive a coherent, helpful answer, you’re not talking to something that understands you in any human sense. You’re interacting with a very sophisticated pattern-matching system that has been trained on an enormous amount of human-generated text.
How did it get here?
AI isn’t new. The idea has been around since the 1950s when Alan Turing first asked the question — can machines think? For decades that question lived mostly in academic papers and research labs.
Progress came in stages. Early AI systems were rule-based — given a set of instructions and expected to follow them. Useful in narrow contexts, but brittle. They couldn’t adapt, learn or handle anything outside their programming.
The shift came with machine learning — the ability for software to learn from data rather than follow fixed rules. Feed it enough examples and it starts to recognise patterns on its own. That was a significant step forward.
Then came deep learning — a more sophisticated approach inspired loosely by the structure of the human brain — which unlocked a new level of capability. Combined with the explosion of available data and the computing power to process it, something changed. AI moved out of the lab and into everyday life.
What you’re using today — whether that’s a voice assistant, a recommendation engine, or a conversational AI — is the result of that long, incremental journey. It didn’t arrive overnight, even if it feels that way.
What AI isn’t
It’s worth setting some expectations — because a lot of what circulates about AI online sits at one of two extremes. Either it’s portrayed as an existential threat, or as a magic solution to everything. Neither is accurate.
AI is not conscious. It has no awareness of itself, no feelings and no agenda. It is, at its heart, a very capable tool. Like any tool it can be used well or poorly, and like any technology it comes with questions worth asking — around accuracy, bias and appropriate use.
But those are conversations best approached from a place of curiosity rather than anxiety. Understanding what AI actually is makes it far easier to use it sensibly and evaluate it fairly.
How I use it
I use AI as a tool — the same way I’ve used every other digital tool across my career in games, design and technology. A tool that, in the right hands, extends what you’re capable of. Faster research, better first drafts, quicker problem solving, new approaches to familiar challenges.
That’s what Nearself documents. Not AI as a threat or a miracle — but AI as a practical instrument, used honestly and evaluated fairly.
