There’s a quote from Eric S. Raymond about the issue of getting people to switch to something better (in this case the OS Plan 9) if there’s already something that’s fulfilling the need just enough that it becomes difficult to get anyone to move.
it looks like Plan 9 failed simply because it fell short of being a compelling enough improvement on Unix to displace its ancestor. Compared to Plan 9, Unix creaks and clanks and has obvious rust spots, but it gets the job done well enough to hold its position. There is a lesson here for ambitious system architects: the most dangerous enemy of a better solution is an existing codebase that is just good enough.
The fear now is that people will just switch to Bluesky until it becomes like Twitter, and it’s not a guarantee that Mastodon will be next in line. It could be another closed service that’s primed to take its place, and thus, the cycle continues.
