What's wrong with that? There are now materials that allow you to have solar panels on a window (so they are not opaque anymore), and we can put data centers under our feet.
Ok I guess my mind didn't think "entire surface of the earth" would really mean entire surface of the earth because that's just abhorrently stupid. I mean, in order to cover the entire surface of the earth with datacenters, we would first need to build stuff on the entire surface of the earth... Which would take... thousands of years? And I'm sure we would grow some trees on top of the data-centers along the way.
In the current system technology is meant to serve the shareholders. That might end up serving us, if you believe the standard narrative. But maybe the shareholders will just carve out a few nature reserves for themselves and just wait for the rest of us to die off.
