SeaSteading Comes to mind
The potential and the possibilities are mindboggling
The problem is that large institutions who have the capacity to do something like this have a serious failure of imagination.
BUT
be of good cheer...the technology..she advances.
wealth is being created at a rate unimaginable in times past
it's only getting faster
and the trickle down theory of economics works
(rilly childish website..they should be ashamed)
The rich get richer..true.
but the poor get richer also
today I have more computing power than existed in the whole wide world
when I was born.
it would have cost Trillions of dollars then.
cost me a couple of thousand dollars now.
same thing with CNC machines..and 3D printers.
almost everything
comparing apples to apples everything is getting
Cheaper.
