There’s something refreshing about explicitly saying “this editor exists to delight me, and that’s enough”. The default script now is that every side project should either be open-sourced or turned into a SaaS, even if that pressure is exactly what kills the weirdness that made it interesting in the first place.

Some of the best tools I’ve used felt like they started as someone’s private playground that only later got hardened into “serious” software. Letting yourself park Boo, go build a language, and come back when it’s fun again is probably how we get more Rio/Boo-style experiments instead of yet another VS Code skin with a growth deck attached.
