It can't tell yet when the output is ridiculous or incorrect for non coding, but it will get there. Same for coding. It will continue to grow in complexity and ability.

It will get there, eventually. I don't think it will be writing complex code any time soon, but I can see it being aware of all the libraries and foss that a person cannot be across.

I would foresee learning to code as similar to learning to do accounting manually. Yes, you'll still need to understand it to be a coder, but for the average person that can't code, it will do a good enough job, like we use accounting software now for taxes or budgets that would have been professionally done before. For complex stuff, it will be human done, or human reviewed, or professional coders giving more technical instructions for ai. For simple coding, like you might write a python script now, for some trivial task, ai will do it.
