Also, the clock speed of CPUs are limited by resistance and heat.

Both of those go to zero. We may see 100ghz CPUs and 3D stacked cpus with almost no need for cooling.

Wouldn’t you still get heat from current switching back and forth and transistors changing polarity?

At those frequencies, induction would be a huge headache.
