An issue you approach but don't quite mention explicitly is dark silocon. The chips are getting smaller but the concentrated heat prevents the whole chip from running at once. If we did run power through the whole chip it would break so we need to leave some of the chip -dark-. This leaves less of a benefit from jamming more transistors on the chip. One way around this is as was said, reduce the heat. Another idea has been to design hardware -accelerators- that can do one job very well, and just specialize different parts of the chip to do different roles. This way we maintain some benifits from shrinking the chip while not requiring the whole chip to be running.

The quality of Crash Course Engineering series has really been falling with the numerous poor choices in words and misunderstandings of key concepts. At 6: 12, it is very misleading to say that nanotechnology is an alternative to standard transistor methods. Instead, nanotechnology is a natural progression of electronic engineering which fits into the Moore's Law narrative where numerous advances in engineering solutions make up what is known as nanotechnology.
TLDR: 6: 12, Nanotechnology is not an alternative, it is the current standard.

Another thing to consider with energy efficiency is _what_ is running on the computer as a well written C++ will be arguably far faster and more efficient than a well written Java or Node program as the C++ program traverses fewer layers of abstraction and is often optimised for specific hardware.

Crashcourse, a suggestion or maybe a request but do you plan to create a video about agricultural engineering and am I correct that it encompasses all four pillars of engineering namely chemical, civil, electrical and mechanical?

The 3% of energy produced in the world being used by computers was interesting. It would be even more interesting to know what percent is being used for doing cryptocurrency calculations.

5: 10 -Calculations per sec per $1000-
Say what now? Where are these human brains being sold? And why is the price not changing over the years?

Goes to lecture, does an entire 3 hours on Logic Memory and Hardware, comes home, puts on Crash Course: Today we're learning about Moore's Law. UGH!

First sentence: -Whether you watch this video on your laptop, smartphone or smart watch --
Me: Is nobody using desktop computers any more?

And the 90 percent of the 3 percent of over energy budget is used by people running an amd system with an r9 295 and amd fx 9590
