Transistors at 7 & 5 are nowhere close to having serious “quantum” issues—that regime is thousands of times smaller than current gate design. Remember that the “size” is a marketing term that really relates most closely to “effective” wire pitch & gate density with respect to processes in the hundreds-of-nanometer scale. The absolute smallest functioning design I’ve read about is IBM’s 7-atom gate. That gate is something like 100thousand times smaller (volumetrically) than current production. Also, current HW design is really inefficient. Think about all the crud between some front-end developer and the server powering the webpage on the backend, vs a ‘native’ app. That’s a good analogy to current HW design and real total-badass low level HW design.
