There were a lot of things that one excited as atoms that are now in the realm of bits so this statement is not true

Electrons don't upload onto the net, they simply enter, follow a path, and exit as heat or light or radio waves etc, they remain as physical as before, and the physical ultimately is what defines the digital, not the other way around. The digital is the physical path itself. That's plenty of space on the digital, just not any measure of actual real space. May the digital have good fresh air.
