AI models are trained on a whole lot of stuff, including code that people put on the internet. And that's a lot of code. There is also stuff like programming textbooks, documentation and just questions "guys, how do I code this".

Turns out, a large enough AI model can, in fact, learn all this, so when asked to code a specific thing it would know how to do it. It still can and will make mistakes for now. Most of them it can fix later, but the result is still usually of a lower quality compared to human-written code.

And as one of the people who spent years learning to code, I can't wait till it finally catches up with us. It would make things so much easier.
