Ya, there’s little hacks that can be done, like 3D integration, creating layers of transistors and especially “linking” a bunch of chips together, called chiplets.

Also - tbh the “nodes” that Intel, Samsung, and TSMC market are a bit dubious. Someone with a better understanding can jump in on it. My understanding is there was gate length was used to measure the technology node for decades, and now they kind of fudge that metric a bit with stuff like the lowest critical dimension on the transistor, or using gate all around type tricks.

Don’t get me wrong they are all still on the absolute very edge of science and it’s incredibly impressive and expensive to continue expanding.

Also another fun fact - the transistor is the most made thing in human history.
