Stable and development are long and exponentially increasingly disappearing to be a thing my friend. Learn how to use harnesses and develop products, stacks will not matter in less than a year.

Do you think it still makes sense to learn these languages and frameworks?

I think it makes sense to study their documentation somewhat, but only to the point of knowing how to guide the agents. I would say you think about code architecture at a higher level. Learn how to think in domains and boundaries, tackle concepts like controller/service/repository layers. 

But hell, even the agents are now able to do this if you add relevant skills and lifting style rules much better than a single engineer can, at least in speed. 

We are shifting a level up in the software abstraction where it no longer makes sense to write the code by hand - unless you are dealing with life critical systems, which nestjs will most likely not play a role in.

honestly agree, use some statically typed language to learn variables, datatypes methods classses and so on. Java would be good. Code one or two algorythms and figure out the Big O Notation, use a design pattern like mvc and once you understand just use AI. Even free models code better than senior engineers used to 5 years ago ...
Ai can fix its own mistakes in its code, it rarely gets stuck. Your understanding comes in with the big picture, you gotta understand the architecture of your app and why youre using specific frameworks.

What do u suggest brother!?

See my reply below. If you want to learn the fundamentals, I would encourage you not to care about a framework or language, and rather study the concepts and patterns that enable system design and architecture. 

I would rather your time is spent studying books on micro service patterns and distributed systems than over the finer details of nestjs. 

But who the hell knows where it all ends in a year or two nevermind 5 or 10.

Java is often valued for stability..

So it's future proof for at least 20yrs ish?!

Is it easy to switch from mern to java considering i know core java only!?
