I have no idea what you’re trying to say here.
If you want to learn how to code, writing a calculator with a ui isn’t a bad idea. But then you should code it yourself because otherwise you won’t learn much.
If you want to try and see if llms can write code that executes, then fine, you succeeded. I absolutely fail to see what you gain from that experiment though.
But there are other people in parks. Why the fuck would I want to deal with their bullshit when I can just have my own park?
