What kind of data centres.
Because I have to tell you, 90% of the people who Have Opinions on datacentres have only ever fucking heard of them in the context of "AI" and they are very very misinformed on what DCs are and what they do. Equating all DCs to LLMs is like equating every single power generation source to a coal burner
tl:dr: outside of LLM shitfactories they literally underpin your modern life.
