While one has the time to think about such things I can see where he is coming from. We have been on this rock for a while and it is high time we stop researching into ways of killing each other. I think we have that pretty much perfected.
We need to branch out. Turn our research to space and exploration more where we can get off this rock and put people on other rocks so that if something major happens to one rock humanity will still survive. I think that is basically what Hawkins is referring to.
Stephen Hawking will test his theory that humans must leave Earth. Let’s hope he’s wrong.

KN,
I don't know about that. Prior to 1750 the population of the world was about one billion people. It had been fairly steady around the number with some minor ups and downs for thousands of years. That was what the world could sustain given the farming techniques of the times. From 1750 to 1950 the population rose to three billion people. Now, that was triple what it had ever been and was a huge surge. This was due to advances in agriculture due to chemicals and advances in medicine keeping us living longer. There are now about 7.5 billion people on the planet. That means it took 200 years to triple, a rise of two billion people. And it took about 65 years for it to go up 2 1/2 times or about 4.5 billion people. At the present curve, we will overpopulate this world's ability to supply fresh water for farming and other needs very soon. 100 years may be a pretty good estimate.
I do not agree. With war and other people doing stuff to wipe each other out I think we can sustain more people but will not have to. I think we can feed more people still. I have a feeling that our current numbers will fluxuate but we will be able to feed people for a few hundred years yet. We still have a lot of area that can be farmed that is currently not being farmed at all.
I hope you are right because at the rate we are going we'll know soon enough. I know there was a study don't not long ago that came to the conclusion that the next large war would be fought over water. It's not land we don't have enough of, it's water to irrigate that and. Also, with global climate change a concern, more people may tip us over the edge. Of course, nature has found a way to restore the balance before, like mass plagues, and something like that could happen again. Zombie apocalypse anyone?
