> provide multi gigabit fibre Internet to everyone nearby.

Kind of a cool idea, actually. These data centers could turn the towns where they build into startup incubators. Offer free high speed internet and heavily subsidized compute to residents in exchange for building there. At least gives back economically somewhat, as a data center itself doesn't provide much in return.

Gigabit internet doesn't power startups. It powers consumer streaming. As long as you can run Zoom, you don't need high internet speeds for startups

how exactly is high speed fiber + subsidized compute a recipe for making startups?
