I thought it was really perceptive. Look at what JS was designed to do cf. what it's actually doing these days.

Turns out it doesn't really matter what domain you were originally trying to tackle. If you've stumbled upon a low friction way of achieving other things, people are going to use your tool for those things, even if it's not the optimal tool for those domains.

I dread the JS/TS future, but it's obviously coming.
