The idea that these will keep being improved on in speed reminds me of the math problem about average speed: > An old car needs to go up and down a hill. In the first mile–the ascent–the car can only average 15 miles per hour (mph). The car then goes 1 mile down the hill. How fast must the car go down the hill in order to average 30 mph for the entire 2 mile trip? Past improvement is no indicator of future possibilit…

41 mph, assuming the person asking the question was just really passionate about rounding numbers and/or had just the bare minimum viable measurement tooling available :)))

You're not joking. If you're like most people and have only a few TiB of data in total, self hosting on a NAS or spare PC is very viable. There are even products for non-technical people to set this up (e.g. software bundled with a NAS). The main barrier is having an ISP with a sufficient level of service.

Sure, hardware is cheap. However if you actually follow the 3-2-1 rule with your backups, then you need to include a piece of real estate in your calculation as well, which ain’t cheap.

I keep a small backup drive at my office which I bring home each month to copy my most sensitive documents and photos onto.

All my ripped media could be ripped again: I only actually have a couple of Tb of un-lose-able data.

I think the opening example involving Google is misleading. When I hear "Google" I think "search the web". The articles is about getting an input encrypted with key k, processing it without decrypting it, and sending back an output that is encrypted with key k, too. Now it looks to me that the whole input must be encrypted with key k. But in the search example, the inputs include a query (which could be encrypted wit…

That’s not the understanding I got from Apple’s CallerID example[0][1]. They don’t seem to be making an encrypted copy of their entire database for each user.

FHE is so much more expensive that it would still be cheaper.
