Someone born in 1885 who lived to be 70 was brought into a world where it took weeks to get from the US to Europe, and died in a world where it took hours. TNT was the hottest in explosives at their birth, and we’d seen the spread of city ending explosives by their death. I personally feel nuclear proliferation is still orders of magnitude more frightening than anything AI has done.

Someone born in 1985 who is now 37-38 was brought into a world where the internet barely existed, and was barely an adult when the iPhone launched. There’s still a lot more that can happen.

Don’t listen to pessimists: the world will look very different, but we apes have a way of adapting.
