Its not about buzzwords but time ranges.

Currently new frameworks are created in dozens and few are required for everyday work and they change each year.

The amount of information newer programmers have to keep pace with is HUGE...

Thats why some companies stop hiring ppl after 30s because they are simply not able (statistically) to keep with all of it. Its also more about not having other responsibilities - family, kids, friends, home, groceries, hobbies, health etc

I really hate that part of IT because its not what we have seen in our hearts when our first "Hello World" did run..
