Technology fatigue: you have just spent the last few years becoming an expert in a technology stack, and suddenly, nobody cares about that stack. Or worse, people start reinventing stuff that was trendy – or possibly even old – when you were tinkering with it as a teenager, and they make all the same mistakes. Happens a lot with the web for the past few years (every JavaScript GUI framework, WebSockets ~ sockets, WebASM ~ asm, WebGL ~ OpenGL, etc.) and in the programming language community (generics, functional programming, concurrency becoming mainstream after the industry spent 40 years decrying them, etc.) Probably in other places, too. Also called Future Shock when I was a kid so even the concept itself is making a cyclic comeback :)
