Related anecdote: My 12yo son didn't like the speed cubing online timer he was using because it kept crashing the browser and interrupted him with ads. Instead of googling a better alternative we sat down with claude code and put together the version of the website that behaved and looked exactly as he wanted. He got it working all by himself in under an hour with less than 10 prompts, I only helped a bit putting it online with github pages so he can use it from anywhere.
