Why are you making a PS3 emulator?

What I wanna know about rpcs3 is how the whole project came into existence in the first place. Did dhrpcs3 just start a github project, and others just heard about it somehow? What's the gap between rpcs3 in 2011 and rpcs3 today and in the near future, because rpcs3 has come a long way to run ps3 games already, even if basically one (swap).

Btw, people still think a ps3 emulator will never happen, or will take decades to load/play games, despite the depths rpcs3 has come in a few years.
