This is just Ol' Yuli coming to remind everyone that we only have one shot at transcendence, and if we blow it, we will never get that chance again.
Should we destroy civilization, there are not enough fossil fuels in easily reachable places for any subsequent society to achieve an Industrial Revolution. We mined most of it and the only stuff that's left requires modern technology to reach.
And though fossil fuels can be renewed, they almost certainly won't be renewed quickly enough for any future civilization to find them useful. Certainly not for any near-future human civilization.
We basically live at the penultimate point of life on planet Earth. It's not too hot, nor is it too cold. There's just enough fossil fuels to get us to the point where we can use post-fossil fuel technology. All extinction-level events (I really refer to them as 'civilization busters' since they probably couldn't render us extinct anyway) took place too far in the past to have any effect on the progress of our technology. We lived on the edge of nuclear apocalypse for 50 years, and we avoided it only through the greatest luck. Climate change has begun, but it has not reached civilization busting levels, nor is it expected to reach civilization busting levels by the time we develop artificial intelligence. In fact, we've begun outpacing our own extinction because of how rapidly our computer technology is advancing.
We basically need only 100 more years. 100 more years of no interruptions, and we'll be cosmic gods. It's increasingly likely that we won't even need that much time.
But if we do get interrupted, and we do stumble... pzfft. That's it. Kaput. Earth dies a dead planet.
No pressure, right?
