Now extend it 10 generations into the future

fascinating clip, alanocu,

you extend it skwirlinator - my job here is done

thanks, Merrie - I thought it was really interesting

Darn, I dunno how to extend it

wish it were possible to extend it and see what it will be like in say, 200 years! great clip Alan!, thanks.

I wonder what name "present" will take on? Great clip!

Wow shame we can't fast forward it, I think little old England will be gone, maybe just the odd mountain in Scotland poking out of the sea.Fascinating, thanks for that.

at least one thing is ever statically sure and that is: impermanence

excellent clip thank you
