> Most of us will get bored without novelty. That's why the software industry has a recycling mechanism to keep things fresh and interesting for us: every once in a while a new, or different, language/framework will rise and light the path for a brighter future, overthrowing the existing standard, demanding that we learn it to be on top of the game.

IMO, new frameworks aren't that interesting in most cases. They're simply a reorganization of what we already know at worst and a watered down version of a new principle at best.

- Procedural programming

- Functional programming

- Concurrent/parallel programming

- Security

- Making apps or web apps

- Compiler construction

- Computer graphics

- Machine learning

and a few other topics, those are new things to learn IMO. When you know procedural programming, then compiler, or database construction isn't obvious at all.

However, the first moment I learned React, I felt it was quite obvious from the get go. Sure, some practice was needed to really be good at it, but the first time I created a toy compiler, I was also trying to grok it and with frameworks that has never been the case (after my first one which was Cocoa Touch).
