On Less Wrong and at the SIAI house, we quickly learn to stop saying certain or "100%". Do you think a Singularity within the next 50 years is 95% likely? 80% likely?

Also, for certain definitions of inevitable, extinction is inevitable without a Singularity. A Type 1 Civilization could at absolute best colonize a few surrounding solar systems, but eventually the stars will burn out. Though a universe where we hit Type 1 but never Type II would be rather interesting.

Though I suspect you'll have to lure Clippy here with the promise of persuading angel investors into funding nanotechnological paperclip foundries.
