Conjecture: Most of the people doing research in the foundations of maths are 'not good enough' for maths. conjecture here is obviously a joke (but not completely). not good enough as in feel that maths is too difficult to understand (i.e not clear enough, too abstract). There's obviously also a personal taste as to why some do foundations and some don't. I got this idea from Hilbert who thought that abstract mathematics was an elegant way of stating mathematical proofs but that all mathematical proofs could be reduced to a concrete and constructive manner. Godel showed he was wrong but the idea can be applied to wide areas of maths. So in that sense my conjecture seems very true.
