I'd be in real trouble if I lost emacs. Probably talking a 90% slowdown in the short term, only really getting back up to speed after I'd reimplemented it. But emacs is free and not-ridiculous to build from source so the dependency causes me no stress.
I can see obsidian ending up with similar effect. That's probably in the same category where it disappearing tomorrow would mean I drop whatever I'm working on to reimplement it, hopefully building on top of some existing alternative. However that one is not open source. There is low level anxiety there. An interesting question is how high the licence cost would get before it was no longer a net benefit.
