how much current can a one atom thick conductor carry before evaporating or destroying itself?

You can sort of figure it out from electron velocity vs conductor cross section with a nod to resistance.

Since carbon transistors are intrinsically higher temperature devices due to the strength of the carbon-carbon bond and also the carbon is attached to some substrate (usually silicon so far) probably quite a lot. We will of course know a lot more when the devices go into production.

A coulomb is an outrageously huge number. An atom is an outrageously small thing.

And yet 1,000 Amp silicon transistors are available.
