Better moderation (to the extent they still care)
Generation of AI slop for the sheep to feed on
Use of AI is really core to their business, so understandable they want to build it themselves, but not so clear why they want to "open source" (weights) it other than to harm companies like OpenAI
I personally think that the population scale surveillance and behavioral manipulation infrastructure built by meta is unethical and incredibly dangerous.
I keep telling parents that Meta et al are spending the inflation-adjusted equivalent of the Manhattan project — not to defeat Japan — but to addict their child.
I think atomic power or even better drugs / medicines is actually a good analogy considering the dual use nature of the stuff that they are building. Can improve quality of life if used prudently and responsibly, or cause devastation if not.
