That is good to know. I expect that one possible future has rising sea levels creating 'cities on demand' on higher ground as people wait to the last minute to adapt. With a capability inland of the level projected by Broad group it would be possible to create housing for over several million people per year.
That said, the capability to house millions of people in 'new' construction over a short period of time (less than a year) is a new capability that is only now becoming possible.
One of the things I try to avoid is assuming that problems that had either no solution or only bad solutions in the past, continue to have only bad solutions.
