There definitely is, and I would suspect that many pure mathematicians have the same worry (in fact I don't need to suspect it, sources like A Mathematicians Apology provide clear evidence of this). These people might be another good source of thinkers for a different side of the problem, although I do wonder if anything they can do to help couldn't be done better by an above average computer programmer.

I would say the difference between the sequences and most philosophy is one of approach rather than content.
