Edit: 3 billion worldwide
Well said Micro. We're headed for a "nice" game of Last Man Standing and it ain't gonna be pretty.

And I wish I had the kind of money it takes to decamp for Kiwiland myself!

I agree, Micro,

Man, I've spent the last 30 years thinking that I really like industrial modernity -- well, at least modern medicine and cars and Interets and all that -- but that having 7 billion humans on the Earth fighting like cats and dogs over resources would just become a nightmare ... which it has.

I suppose the "optimistic" answer is to build thousands of Arcosantis where we can all live in little cells in the beehive, but this to me is not about what humanity and freedom and dignity are all about.
