That is not true, I have never seen robots in datacenters.
granted you do not need a large crew, like I said 40 for a large hyperscale center. Maybe 6-10 for a smaller one, not including security.
however there are a lot of people offsite who make use of them it is not like they are all autonomous. Someone has to tell the individual computers what to do.
for example AWS or Azure. yes there are large datacenters, but the capacity is rented out to whoever pays. I have had both Aws and Azure instances sometimes lots of them. there are lots of people and companies like me that create jobs offsite.
do I like the cloud ? do I like datacenters, not really so much, but there is a lot of BS propaganda about them and I have looked into the funding a bit just cause what I see is so divorced from reality.
