That's not prepping in the sense of having a bunker full of canned beans. Its taking control of a key piece of my business, and likely saving money in the long run.
A large company might own their equipment, but an individual operator probably won't. So it might make sense for some large software companies to own their LLM hardware, but it probably won't make economic sense for individuals.
Of course the economics are different in different industries. Trucking owner operators account for ~15% of truckers, but buying a rig is six figures against 5-6 figure income. Buying a mac mini is 4 figures against a 6 figure income, so maybe lots of people will do it even if it's not economically optimal.

same goes for renting vs buying a house, or anything.
the breakeven point here would come when they stop subsidizing the subscriptions, or when local ai gets to run on basically everything, making it ~free (sans electricity)
