We only have to look at ourselves to see how intelligent life might develop into something we wouldn't want to meet.

If it were only a few degrees, that would be serious, but we could adapt to it. But the danger is the warming process might be unstable and run away. We could end up like Venus, covered in clouds and with the surface temperature of 400 degrees. It could be too late if we wait until the bad effects of warming become obvious. We need action now to reduce emission of carbon dioxide.
Interpretation
What this quote means
The quote emphasizes the urgent need to combat climate change before it's too late.
Stephen Hawking warns about the potential consequences of climate change, likening Earth to Venus if actions are not taken to reduce carbon emissions. He stresses the urgency of addressing global warming and suggests that waiting for its adverse effects to become apparent could lead to catastrophic consequences.

It surprises me how disinterested we are today about things like physics, space, the universe and philosophy of our existence, our purpose, our final destination. Its a crazy world out there. Be curious.

The world has changed far more in the past 100 years than in any other century in history. The reason is not political or economic but technological-technologies that flowed directly from advances in basic science. Clearly, no scientist better represents those advances than Albert Einstein: TIME's Person of the Century.

It seems sensible to discard all hope of observing hitherto unobservable quantities, such as the position and period of the electron... Instead it seems more reasonable to try to establish a theoretical quantum mechanics, analogous to classical mechanics, but in which only relations between observable quantities occur.
