I would consider cold storage to be preferable, but running at a low speed might be necessary for self-defence and what essentially amounts to data verification, the ability to rebuild to a certain redundancy level.

In my view if time loops immutably I gain nothing: same program, same input, same result.

I fully expect to die and I think I am ready for it, but I'm going down fighting. In terms of abstract moral questions, ten years of Catholicism cured me of any curiosity I had for that sort of thing.
