"A" for "Average"

Written on 2026-08-25

Ask AI to write something in a language I're familiar with, and… well I'm never super impressed. Yes, it works, yes it needs finetuning and polishing. That's fine though, it can be a huge productivity boost to help get you started.

Ask AI to write something in a language I don't know, and… my mind is blown 🤯. "How can it possibly be that something I don't understand, AI does so flawlessly??"

Now, taking that first experience into account, how big do you think the chances are that AI just happens to be a master in a technology I don't know, while it was average in a technology I do know?

Or… could it be that the quality of both contexts is the same, but I simply am more impressed by one of them because my understanding of that second context is much more limited? It's like a magic trick that's impressive as long as you don't know how it works.

What I find crucial to remember in this era of AI is that LLMs are essentially big averaging machines. They predict the next word based on what's most likely within a context. That is it. Don't get me wrong: we can do amazing things with simple technology; we can even turn something as simple as 1 and 0 into whole computer systems. The point isn't that AI is either good or bad, the point is that — by design — it will lead to an average result at best.

Of course, "average" — by definition — means that some people will be below average, just like me when it comes to using a language I don't know. That doesn't make the result objectively better though. It's still average, overall.

Let's not forget that.

Things I wish I knew when I started programming

This is my newest book aimed at programmers of any skill level. This book isn't about patterns, principles, or best practices; there's actually barely any code in it. It's about the many things I've learned along the way being a professional programmer, and about the many, many mistakes I made along that way as well. It's what I wish someone would have told me years ago, and I hope it might inspire you.
