Professor Brailsford is my favorite presenter on Computerphile.  It's just really warming to hear him tell of where technology has come from from.

+Computerphile Yep, inspired me, I started coding on a BBC as a child and I ended up being lectured by Steve Furber at Manchester Uni, a great mind, I think myself lucky to have been taught by him :) Thanks Steve. PS: Margins on the BBC were small, I remeber we had to wait for ours to warm up for 30 mins at least, then hit it in a certain place to get it to do it's single beep into life, and sometimes you had to sit on the external floppy drive to remove artifacts from the screen (looked like noise in the framebuffer).

+Computerphile x XOR 1 is NOT x

+Karreth belgium here, we just A v B and A ^ B (the ^ should be on ground level).

why wasn't addressing or selecing the output (read bus) covered? I guess it's fairly obvious how, but would have been nice to see a complete example. Also, most memory is based on DRAM technology which looks nothing like flipflops, I believe this is closer to an example of an SRAM.

"Is it going to benefit the user in the long term" is a good question. Glad people are asking and checking and improving on it... unlike in Windows 8. ;)

+Francis Moodling everybody makes videos about it, but seths explenation was the best!
