So it looks like the person who set up this GitHub repository didn’t even make the software that does all the actual work. They also never mention the original author in the README. But, of course, their AI prompt includes instructions to open their homepage, so this is effectively using the AI prompt for indirect advertisement. The HN submission title is also misleading. I didn’t see any maths in the repo.

Grep-and-replace? You mean, sed? People burn tokens instead of using sed? Honest question.
Mediocre programmers use AI to write sed one-liners for them and then brag about AI productivity boosts.
And experts just use sed directly and then they wonder why everyone else is raving about AI.
Aside: The speed at which AI can spit out complex diagnostics is nuts. Par is usually half a second for a dozen complex shell commands tailored to the exact problem at hand.
