I would guess a swappable battery would be separated from the vehicle, similar to a gas bottle for a grill.

The battery would be rented for a small deposit and on swapping you only pay the energy + service fee.

I guess you could also buy one to own, but then could not swap that.

That’s how it would make sense, at least.

I mean, other file sync apps upload everything to a third party while you’re working with the device.
Then, when you use another device the first one can be turned off.

Then why does the kernel have a crypto API?

Checkmate, Satoshi Torvalds!

Most x86 EFIs are, so the comparison is not really fair.

That’s Canonical building Mir 2.
