I explained the reason that the West gained an agricultural and then industrial revolution which catapulted us to orders-of-magnitude higher productivity and standard-of-living compared to the East (i.e. Asia).
Make sure you click the link above and read the entire linked blog post to understand deeply what I will summarize below.
It was the network effects of pursuing the maximum division-of-labor and the early analog of the Internet in form of an efficient transportation network focused on using arable land for producing horses instead of pork and human porters that China chose.
You’re advocating the world will make the same mistake as the Asians did and prefer to choose lowest cost instead of highest advance.
Sure it’s cheaper (as in cheapskate stupid) to sprawl out on land horizontally than to build tightly vertically integrated knowledge age global village pods, but so were human porters cheaper than horses.
Your computation also fails to factor in how much more efficient (less costly) robots will be at constructing everything. The cost of robots has been decreasing exponentially. It is just like the first calculators in the 1970s that cost more $500 inflation-adjusted. Now they cost $10.
I have just taught you a very important lesson. Don’t ever bet against technological advance. Ever.
P.S. I am not trying to be condescending nor act like I know it all. I am just reasonably certain about this conjecture about land becoming worthless as we leave the fixed capital investment ages and move into the non-monetary knowledge age. Highly recommend you click that link also.
EDIT: also a follow-up which I wrote on bitcointalk.org in the context of prior major collapses of civilization into Dark Ages.
