Hopeless. As foundations of mathematics, it is conceptually completely
incoherent. Proponents are zealots who want to hide this from you in the
worst way. As technical mathematics, some of it, in moderate doses only,
has limited and respected uses - it helps with the formulation of
appropriate generalizations, and cleans up some proofs.
