Do you dig your garden with an excavator?
"Would you rather have worse software for literally no benefit?"
We should aim to make software as performant, bug free, feature-complete, and maintainable as is cost effective. It's asinine to argue that software shouldn't be fast, not because of some trade off, but just because someone doesn't need it to be fast for small tasks.
Which, mind you, isn't even the case here. Thousands of businesses use typescript for millions of lines of code. Performance gains can mean tens of thousands of dollars in compute or hardware or time; tons of carbon saved from being emitted.
the analogy is not between each specific consequence/cost, it is relative to "single axis optimization" not being a solid strategy
