For mainstream programmers they are, in that they have features they never saw before. You know, like in "it's something new for me" or something like that. The fact that objectively some of those languages come from '50s and '60s (like Lisp in '56 and ML in '63 IIRC), which makes them ancient by today's standards, doesn't matter. It's really sad. I devoted a couple of years to learning about and trying to use such languages (see here[1] if you want) but I'm in a very small minority; most young programmers never use anything other than 1-3 core languages they learned; the number of known languages increases with years of experience, but it's still biased towards currently mainstream languages. Which are mostly crap. Anyway, that's how it is: most programmers are very conservative in their choice of tools they use and feel no need to look for alternative tools to use.
