I was on the hype train for quite a while jumping between different systems and burning out a lot. It's mainly because I entered web dev when javascript was beginning to eat up the world. Its the only language I know and understand well. (learning Rust and dart now) Lots and lots of ideas and frameworks keep coming up. Now when i read stuff for the backend its pretty calm and steady. Especially in the java stack. I used to laugh at people writing java. I complained that JVM takes a lot of memory. But I didn't see that JVM still completed >98% of the requests whereas my Node app was completing only around 65% of them. The memory mattered in my laptop but not in the server.

Now we rapidly prototype features in Node and move them to java once the consumers like those features. Even though the stability of an application depends on the programmers, its a good decision to use well tested and stable stacks.
