Mostly agree with what you said, but just throwing this fun tidbit out there. The stated nm "size" of transistors are no longer accurate (and haven't been for some time). For example, when a company says it's manufacturing at 16nm or 14nm...that is the size in which the chip designs are drawn and planned, but the physical size dimensions are closer to 20nm. Same will be true when they go down to 10 and 7nm, it wont actually be a 7nm transistor in physical dimensions. And as far as lithography, right now they're mostly looking at "extreme" ultraviolet wavelengths but the problem is mass producing is not currently feasible with with how long it takes the photoresist to react. That being said things like quadruple patterning allow them to get pretty small with EUV wavelengths.
