is there a physical limit to how dense integrated circuits can be before we start having problems? i know about moors law, but i'm not asking about cost vs. benefit, i'm asking about the fundamental limit to how many logic blocks we can form per unit of area on a chip.

I'm just a dumb /p/hag, so enlighten me. Rather than make the components of a CPU smaller to fit the size of existing processors, why not just double the size of the CPU to fit more components and create a new standard?
Think of a bag of rocks. Instead of making the rocks smaller, why not just get a bag twice as big? Now instead of one rock you have two rock.
Larger CPU = more transistors = more heat, basically.
As well, signals would take longer to propagate across the IC which means you have a lower maximum clock rate.
It's probably one of these two things that holds IC manufacturers back. They are big companies with deep pockets, if the problem could be solved as simply as that, don't you think they would have done it already?
