My calculator has never given me a wrong answer, so I trust and use it. Every time I have used ChatGPT to solve a coding problem it has had missed important edge cases or been flat out wrong. I find most tasks significantly faster to do myself, but I have found inspiration in a wrong answer that ChatGPT has given me.

Maybe it's good at trivial stuff, but then I don't need it for trivial stuff so why use it then. This example is more like saying you'd use a calculator to solve (5 / 10) when it's faster to solve that yourself.

Now if I was just learning my times tables, sure I'd use ChatGPT, but once I've learned them it's not helping me on the basics anymore, and may be actively hindering me.

You seem to be saying that you're getting a speed-up even in the first case, i.e. where you can write the code without having to think hard or look anything up. If so, how do you do it?

You got it mixed up. Yes I can write some code (multiply on paper) without looking it up but it will be slower than asking GPT and then doing cut and paste with maybe some little editing.
