At what density?
I mean sure if you have a single device in isolation it might be able to cool in a few nanoseconds. What matters is the density at which you can have a checkerboard of these things toggling in opposite directions without neighbors inducing failures.
Otherwise we're simply trading the propagation time of electrons for the propagation time of heat rather than the propagation time of light.
Light may move fast, but heat doesn't.
Edit: also, I'm skeptical about power efficiency if the principle of operation for this thing is fundamentally based on turning free energy into heat. Generally heat is a waste product of the switching event, leaving hope that future generations can continue to reduce that waste. Here, the waste product is what makes it work, meaning that it's probably very inefficient (joules per switching event) and unlikely to improve much. Current mode logic is wicked fast, but never caught on (except for I/O drivers) because fundamentally it works by burning up energy into heat -- it's crazy inefficient and hasn't improved after 20ish years.
