- Claude, please optimise the project for performance.

o Claude goes away for 15 minutes, doesn't profile anything, many code changes.

o Announces project now performs much better, saving 70% CPU.

- Claude, test the performance.

o Performance is 1% _slower_ than previous.

- Claude, can I have a refund for the $15 you just wasted?

o [Claude waffles], "no".

I’ve always found the hard numbers on performance improvement hilarious. It’s just mimicking what people say on the internet when they get performance gains
