Nvidia is already making a 21-billion transistor chip on 12nm..

Personally I can't imagine anyone going smaller 2nm without changing the laws of physics.

Then again, as a kid, I couldn't imagine a storage device capable of holding millions of disks and carts.

It's important to understand there is a lot of un-used vertical capacity. Despite being some 20 layers thick, a modern CPU is still planar and those 20 layers are still thinner than shrink-wrap. Much thinner. So there is the capacity to build vertical..

Does the term "cost effective" somewhere relate to this? I mean it might be technically possible to go 10 nm or even 7 nm, but if the costs for manufacturing, cooling etc are much higher than for the 14 nm, will enough customers be C-R-A-Z-Y enough to pay for that?
