There is nowhere to go, not with the available physical space.

Where we are now is the "nowhere to go" of not long ago.

I had a Kodak DC-1. The notion of "a digital camera the size of a sugar cube" was laughable. Now we've got something even smaller taking pictures most people can't distinguish from a DSLR.

I expect the next breakthrough will be using the display itself as a platform for a phased-array "light as electromagnetic waves" sensor, allowing a software-defined virtual lens for a large-format imager (and oh so much more).

Nowhere to go? We've done amazing things with that nothing for the last 30 years. We're not gonna stop.

Yeah, but a lot of the limits we're hitting are tied to physics. But hey, we're used to trade offs and will go for slightly lower quality in exchange for ease of use and convenience
