"Electronic circuits" still have significant room to exponentially grow and become more complex... And thus will enable new rendering paradigms.
TSMC 3nm is not really using 3nm sized transistors, it's an advertising term to make themselves look cool and isn't representational of any geometric feature sized of the chips themselves.
In-fact the transistors are actually much much much much larger, so we are a long way from reaching peak-silicon when Quantum Tunneling becomes a physical limitation.
And once we are unable to go smaller, we will start to go higher.
NAND started to do this as the smaller you make NAND cells, the more unreliable they become, so manufacturers started stacking instead.
At the moment we are still taking a "hacked" approach to rendering by using Rasterization and -sprinkling- a tiny tiny tiny amount of Ray Tracing on top.
We are far removed from a full rendered Ray Traced rendered game world that represents photo-realism in the truest sense.
And that is still years away.
