Apols if this is of only peripheral relevance as I have not watched the video...
....But, a while ago, I took an electric toothbrush apart. Inside, I found a PIC Microcontroller that was presumably used to control things such as inductive charging, low battery indicator, and motor speed. And also to provide gimmick functions such as the two minute timer that 'pulsed' when it thought my teeth were clean enough.
I would hazard a guess that the PIC in my toothbrush probably had orders of magnitude more processing power and memory, compared with the Apollo guidance computers. I can't quite decide whether that 'proves' that it should be relatively easy to land a toothbrush on the moon?
