I wonder if at some point (hopefully not that far from now) there's some breakthrough or development that would allow FHE in GPU.

I'm guessing maybe that could be a front where the unused GPU power can be taken advantage of in desktop/mobile, besides desktop.

I could imagine some sort of algorithm/driver/framework plus a protocol that would allow remote services to make queries on your personal files (without privacy issues), while being accelerated by the client's GPU.

Obviously I'm talking out of my behind here but I hope maybe someday someone will figure it out.
