Technically impressive though
Without arguing with the rest of the comments here (I agree with most of them) it does seem to be a very impressive achievement. I looked at Homomorphic Encryption a few years ago and run times 100,000,000 longer than on unencrypted data was a bit of a stumbling block, So even keeping the volume of data to process to a minimum, producing results in near real time is a very impressive feat - at least to me!
But I do wonder how easy it is to crack the encryption, compared to AES256. Anyone know?
