CMOS especially, which consumes energy in direct proportion to the square of the frequency because a level crossing is a virtual, instantaneous short-circuit across the chip's power rails. As such, future chip will likely be driven to reversible / adiabatic tech because cryptocurrencies, AI and more are guzzling energy ($$$ and running more circuits) and dissipating more heat that can be sensibly handled in a given unit volume (per-socket thermal characteristics; chilled water plant capacity; forced per-cabinet cooling or submersed in mineral oil).
