The equation relates power consumption, clock speed, and number of transitors to technology size. Ass the fabrication limits dropped, the power use and to an extent the clock speed could go up and the number of transistors massively increase. But the technology is approaching atomic scales, and the clock speed cannot get much higher as propagation delays across the chip make the clock a different beats on different parts of the chip.

Many of the early analogue ICs are still in production today, for example. We could still be using Z80s, as it only ceased production last year. -- Those who want slavery should have the grace to name it by its proper name. They must face the full meaning of that which they are advocating or condoning; the full, exact, specific meaning of collectivism, of its logical implications, of the principles upon which it is based, and of the ultimate consequences to which these principles will lead. They must face it, then decide whether this is what they want or not. Ayn Rand.
