As I come to grips with the limitations of SNARKs for mechanisms that have a mix of private and public data, I have a question: what do you think about FHE? Do you think the advances of the last 2 years will lead to a Moore’s law in practical code, like we saw post Groth16 or not?

FHE still has practical limits that preclude it from being a "magic black box", namely you have to gatekeep the final decryption step somehow, and it ends up in practice often having similar constraints to MPC. So I definitely look forward to it (as well as side quests like much better PIR) but it's not a panacea

And of course better FHE almost certainly translates into better witness encryption and/or obfuscation if we can ever make that viable in practice.

Yes although I’d argue the communication complexity (in rounds) ends up being lower although you have to have more bandwidth (e.g. decryption ideals) per round; but point well taken
