What this skips over is that some languages are better than all others in a domain, sometimes multiple domains. And also some languages are not best in class in any domain.
Would you pick Brainfuck over Java for anything (real)?
If alternative programming exercise counts as a domain, then yes ..
along with Turing Tape machine coding, corewars, that one from Knuth ..
outside of that domain of interest, not so much.
But that is one domain of interest.
It's also true that real world industrial scale dam control isn't a killer application domain for Brainf*ck .. but FGS, have you seen many SCADA implementations?
