Because current AI products attract huge investments and do not pay off at all. Basically they companies have unlimited money, and spend them on building huge data centres and facilities. But as soon as finding will run out, they have to moderate appetites. Many companies will flop and go bankrupt or just switch to something else. Cheap and local LLMs with high efficiency/cost rate should be dominant, as they won't need so much infrastructure to support. Kinda similar was during dotcom bubble, but average person didn't knew and care about ecology and ethics so much as nowadays.

That's why I hate when "morally impeccable" people find an easy target, make it a scapegoat, and bully them online.
