FHE can be made IND-CCA secure in practice (i.e. for specific systems), please stop spreading misinformation. It's impossible in the general case for obvious reasons. Also, TFA isn't about FHE, it's about iO.

I know and have worked with the organizers of RWC and they've done a lot of the kind of work that you're dismissing here (which would be like telling Diffie and Hellman to piss off in the 70s because public-key crypto isn't IND-CCA2 secure without additional assumptions).

I'm decrying the sensationalist writing in this news story, especially the headline, not dismissing anyone's work.

Maybe should ask your RWC organizer friends if your take is proportional to what I'm doing.

I'm a former cryptographer and the headline and news story aren't sensationalist by any means. iO has been considered the "Crown Jewel" of cryptography (by cryptographers) ever since the 2013 iO candidate by Sahai, Waters, Gentry, et al, and Sahai/Waters' followup "How to Use Indistinguishability Obfuscation." From a cryptographer's perspective, being able to use iO is like having a superpower.
