If we are running out of transistors to place on a chip then why not just make the chips bigger?

Question

Basically the title. I was reading about how we will eventually reach a limit on the number of transistors we can place on a chip and will have to turn to quantum computing in the far future. So why not just make bigger chips to accommodate more transistors?

Answer 1

At some point, and at some clock speed, the speed of light becomes a factor for how far apart 2 parts of the cpu can be before the speed at which electrical signals can propagate becomes a limiting factor
