This is from a Reddit Ask Science thread - in the /r/AskScience sub-Reddit the only answers permitted are accurate, and in-depth explanations. 

 

There are responses from ex-Intel process engineers, electrical engineers, nantechnologists, etc. (they talk of CMOS, Moore, specifics of size reductions, etc).
