Hear, hear. There must be 100+ "frameworks" out there, all for the task of rendering a web page. If you learnt them all, you would be stupider than when you started. Pick a handful of technologies - ones that will last - and get deep into them. Step off the crazy treadmill and go for quality, not quantity.

If you had gotten into a "full stack" (lol) of Unix, Oracle, C++ in 1994, you would still be very, very employable today as long as you remained more or less current with them, and you'll still be in 2024. Whereas if you learn "frameworks", you'll be starting again from scratch every year or two.
