Indeed, no conspiracy theory - data centres require a considerable natural resources to cool, and electricity to run. This has been well documented; as is the amount of compute to create the Gen AI animations (like the Battlestar Galactica video referenced above (very nice, but VERY wasteful IMHO). Nor is it a conspiracy theory that the demand for data centre builds is putting an extraordinary strain on memory and storage supply and, as a result, driving costs up for other things. All well documented by the people designing, supplying hardware for, and building these data centres.
Ethics? I can only speak for myself but the creation of these types of mindless Gen AI animations is a horrible wast of compute. Social media is full of stuff like this packed into feeds with ever increasing demand. Not a good thing IMHO.
