Because for those who don't understand or explore other paradigms their skillset is limited. There is a lot to be learned in concurrency domain from functional paradigms. Take a look at intel threading-building-blocks which is a modern way to look at concurrency and it is very much using functional concepts. For instance, parallel_for, parallel_reduce, parallel_scan. Reducing side-effects improves potential for parallelism.

That has never been a problem in a large part of the programming job market. If your skill set fills the job opening a big coorporation or institution has, and that job sets you up for life (instead of the frantic contract based work for startups or small companies) then exploration is a luxury, but in no way a necessity.

Note that logic applies here: I'm questioning the "you should know" claim, not claiming "you should not know" because that would be ridiculous. Learn all you like if you feel that gives you a leg up, or an enriched quality of professional life, but it is absolutely not a requirement in a well-paying part of the real world's programming landscape, so claiming "one should" is a little rich.

Well, this is true if all one is interested in is getting a job today.

However, the best developers aren't primarily concerned about getting a job or not, they are genuinely interested in programming as both an art and a science. Money and jobs is secondary (and readily available because such individuals are more skilled than those that limit their pursuits).

Anyone who stereotypes the practices of the best developers is kidding themselves. Some of the best developers I know only know C.

In reality there are roughly two types of tech: staples and new ones. Staples are around for a long time, but HN tends to focus on new ones. The thing is, even our modern staples came from a much larger set of new pieces of tech.

What this means is, that if you're using a piece of tech that has been popular for at least 20 years, you're probably good for at least the next 20. If you keep switching to the new hotness, you will have to keep doing that because you are most likely learning stuff that won't stay around.
