But you would be banning trains if they were built to just run smack into the centre of town squares loaded with bombs, rendering the cities to dust, as a part of their design and boasted about by the owners.
At least until the maniacally evil train ownership debacle was better organized to prevent such harm in their core application.
There are datacenters all over the place and have been for a very long time. Some of them host physical servers for people and companies, maybe only a literal closet somewhere in a building. Others are giant hyperscaler datacenters that have tons of 24/7 lighting and are the size of multiple football fields.
We need to be very careful here, or we're going to throw the baby out with the bathwater.
I think that perhaps your perception of the impacts of data centers is a bit over the top.
