Me : Not a lot. Efficiency is a short term win, however Jevons Paradox means we will just consume more. Energy consumption will go up and you really need to think about energy provision.
Me : Depends upon who you talk to? I know some VCs who think the solution is spaceships.
X : Spaceships?
Me : Yes. Of course just not for you, for them. You're the underclass. No-one cares about you.
Me : Well you should be doing something about it. You probably won't, I suspect most people in IT are apathetic to this - or if you like your truth less harsh, too focused on making money (mostly for VCs).
Me : Of course, what else do you expect them to do? Elysium is a blueprint for our future until the underclass (i.e. you, me etc) do something about it.
Me : Seriously? I know of few places more apathetic to it, the focus is almost always on money. Take crypto currency, it's a laissez faire dream (sic nightmare) where environmental issues have flown out of the window.
