the datacenter demand wouldn't evaporate, it will probably change instead - i expect that the datacenters will soon be built like pre-fab homes or like the Liberty ships - the fastest ship was built in less than 5 days.

In such a module-based construction you can optimize layout and the fabrication sequence so that the labor is minimized and simplified - like for example you'd be simply laying down wire instead of running it.

Thus the modules can be fabricated where the labor is cheap and plentiful and with high degree of robots usage while only final assembly would require high cost labor at the target location.
