The thing I am failing to understand is if users embeddings can be moved across the Atlantic. The regulation is really not clear about that. I mean, if my browsing habits / purchase preferences can be compressed in an array of 512 floats that is gibberish (and for all intense and purposes a 1 way function unless you have the other tower of two towers model for recommenders) does that break regulations? If it doesn't, I am failing to see the technical problem that Meta is facing, especially considering all the resources and engineering manpower they have. A quick back of the envelope calculation for a worst case scenario tells me that assuming 1B users and 1B ads corpus * 512 * 32 bits that's around 30 TBs to move to keep US and EU users and ads portfolio in sync. Considering the connectivity that Facebook already has between US/EU and the future capacity (https://www.zdnet.com/article/nec-scores-deal-to-build-facebook-transatlantic-half-petabit-cable/ https://www.zdnet.com/article/nec-scores-deal-to-build-faceb...) these can be recalculated and synced multiple times per day. And if moving embeddings outside of the EU is not allowed, they could create temporary ones for the users when they are browsing in the US. Considering that the vast majority of EU users in the US are there for holidays/short stays I would also expect the purchasing habits to change since they are in a different mood/context. So I think this is a PR stunt to avoid doing the extra engineering work and managing investors expectations.
