The 60 mV/dec limit applies to all materials, not just silicon. Beating it will require a fundamentally different type of operation. Agree that changes in materials will require massive investment and learning.

There are transistor designs that can subvert the subthreshold swing limit, see NC-FETs and TFETs.

Sure, but many materials have much higher electron and hole mobility than silicon has.

He's talking about the Boltzmann limit of MOSFETs
