I don't know if Satoshi Nakamoto is alive or dead, and I don't eally care about knowing such info. The most important fact is that Bitcoin itself is alive and keep growing fastly with time. Satoshi is just the creator and I think its not important to know about him
Well.....it IS kind of important considering he made one of the largest invention in CENTURIES.
Bitcoin is just a start. look at all the new altcoins and their advanced technologies.
If Satoshi is alive, I would hope he could work on new Blockchain technology!
