I'm in good health, pretty happy, and have no wish for material wealth. But as a curious theoretical computer scientist, this is one of the great questions, closely related to P vs NP. Basically, it asks if all of our current public key infrastructure is safe in the absence of quantum computers (which I don't expect to see in my lifetime).
