Can I take a moment to appreciate you as the only person so far to meaningful engage on this. It's extremely late here so I won't respond now (other than in-short saying things like Stuxnet still make me sceptical about the validity of verifying the software running is actually what you think it is, and no, supervision requirements aren't the same because we don't have to indefinitely supervise our paper ballots, but you absolutely do with voting machines if you plan on using them again).
I will respond in full over the next day or two, but just wanted to send you thanks for actually making solid, reasoned arguments, unlike others who seem to be pretending like the existence of badly run paper elections somehow proves me wrong, which is very frustrating!
