I'm not sure of anything but our potential. It's only been roughly 150 years since the first internal combustion engine. Today a 50lbs machine mows my lawn by itself by communicating invisibly with hunks of metal in outer space traveling at 17,000mph around earth to determine its position on the face of the planet within roughly a few centimeters. This machine cost me roughly a week of labor. I think the much more interesting question is what sorts of extinction events do you think we will be incapable of preventing in 1,000 years?
