The government appears to be making a big deal about datacentres (AI or not) being a huge growth area. The reality is that datacentres, once built, employ virtually no-one - a handful of security guards and that's it. Maintenance, repairs, cooling and power, racking and cabling of servers, storage, and networking kit is intermittent and done by specialists brought in for the job. Most of the time datacentres are a (very noisy) ghost town.
Datacentres are all managed and run remotely by SREs (site reliability engineers) who can be stationed hundreds of miles away, and often in a different country.
YABU: Datacentres will provide thousands of high quality jobs in neglected parts of the country long after construction.
YANBU: The government is having the wool pulled over its eyes by big tech companies who, even if all these datacentres are completed, will never employ more than a handful of locals in low pay occupations such as security and cleaning.
