Matt Williams also did a great long piece last month on the Transcension Hypothesis. I highly recommend it.
In it he explains more on why advanced intelligences never become Godlike and never become fully virtual. They are always tied to physical reality, doing physical things. They just do that in ever denser environments.
Did you know that 75% of Americans already live in just 3% of the land in our country (urban space)? That percentage may go higher in coming decades. Even when we can live anywhere almost all of us want to live near others, as so much more can be experienced, created, and discovered in such densified and dematerialized environments. At least that's how I see it. Would love others thoughts on this major question about our future :)
