Encryption or not, if it's on somebody else's server, it isn't yours. I don't believe Google has my best interest.
This kind of attitude is really disrespectful of decades of progress in cryptography. Without even considering homomorphic encryption, classic encryption is specifically designed to make intermediate nodes such as ISP dumb pipes that do not know the contents of communication. The ISP can store your communications on their server however they want.
If you don’t agree with this model, I’m afraid modern cryptography doesn’t have anything to offer.
It can give you confidentiality without availability. Not sure about integrity? Anyways, still useful.
It's FHE for "cryptographically-secure private AI inference" not for every other service where they snoop into your behavioral information.
With Fully Homomorphic Encryption it's nobody elses.
The basic idea of of the project is to remove the need for trust.
