Stopped at "Imagine you live in a world where no part of the build has to repeat unless the changes actually impacted it." because I'm already in that world by using Nx and Nx Cloud.
I must admit I'm a bigger fan of the wireit[0] approach, the only pause I have is its a Google project, my temptation is to fork it. The code isn't terribly complex
My biggest complaint with NX is: lack of a sane API for plugins, and it has more overhead than I'd care for. For the amount of complexity that NX has, I'd rather use Rush[1] which gives you everything NX does. My only complaint with Rush is that its development is really slow going, they really need to focus up on Rush plugins (they're good, but still experimental, and I'd love to see them clean up how `autoinstalls` work to be more intutive)
I'm on the fence about turbo from Vercel
