    Size is not the only limitation imposed by physics. And the biggest reason we want to make chips small in the first place is electrical signal travel time, one of the limitations that has been around forever. Another way we’be been approaching it is parallelization, and there is no limit imposed by physics in sight there. Another limit we’re not even close to is the optoelectronic switching limit, which is 1 petahertz.
