This is a weird comment to me. Think about green energy, specifically solar panels and wind farms. Almost by definition, the jobs created are only during installation. (Ok, there is a little bit of long-term maintenance, but a tiny fraction.) Would you say the same about those projects?

It is unavoidable that the modern world needs data centers (how many is open for debate). It is a fact of life that most of the jobs associated with data centers are during the installation, not the ongoing maintenance. Again: Are you trying to say that building any and all data centers is bad for your reasons?

I will give another example: When a company builds a highly automated factory, the same occurs. Inside the factory, there are very few highly skills jobs. Most of them are low skill (moving boxes and refilling automated machines that are cheaper than automating the work). Again: Are you saying that we should not be building these highly automated factories for your reasons?
