Yeah I think it would be possible for simple compute/tallying operations to be held in a sort of RAM-like memory and even processed (extremely quickly given RAM's bandwidth) before being written to anything with storable memory.

It's sort of how our computers work already, but the RAM cache/load-use ratio compared to the HDD storage media-use ratio is inverted in this case.

This is just a theory, but also one based on tech we already have and have had for some time, just set up with a different use-case in mind (handling essentially untraceable data processing/compute).

That said, the algorithms needed to be accessed from somewhere, but if they were clever (ha) then they would have used the backdoor/internet connection for that, possibly making that part untraceable.

We shall see, because I don't think they are this clever, but then again these evil bastards have unlimited money and have captured some of our species' most brilliant minds in their coercion.

Luckily, we already know who wins, we just don't know exactly how we get there; NCSWIC.
