Kudos to funders @neenap.bsky.social and @bloombergdotorg.bsky.social and all of the contributors for the moral clarity of this work.
At the launch of the @thelancet.com series on ultraprocessed foods, the speakers are making it crystal clear: the economic engine we use to produce the food system is hopelessly -- and dangerously -- at odds with societal goals for people’s health and the environment.

Smells like car bloat:

Incredible- Meta projected 10% of its 2024 revenue would come from ads for scams and banned goods, documents seen by Reuters show. And the social media giant internally estimates that its platforms show users 15 billion scam ads a day."
Meta earns $3.5 billion every six months from showing Faceboon and Instagram users 15 billion “higher legal risk” scam ad impressions a day, internal documents state.
That haul vastly exceeds how much the company expects regulators
To fine it for running scam ads.

Business has long depended on emotional attachment as strategy to create switching costs. (E.g., Cadillac). Seems utterly obvious that despite their ethical commitments, the intentional engineering of AIs to generate human emotional attachment will soon be mainstream.
