As long as the official count is actually done, then that's fine... but there's a natural human tendency to want to skip unnecessary work. And any polling place where the workers get lazy and just rubber-stamp the machine's counts have now made it possible for someone who hacks the machine to get away with it.

The machines should be kept air-gapped, not connected to the Internet, and all that. But again, human nature kicks in. There have been some poll workers who swore under penalty of perjury that in their polling place, there had been election machines that got an over-the-wire software update on Election Day. That's just... all kinds of wrong, if those reports are accurate. It doesn't prove cheating, but it does prove that whoever was in charge of that polling place should be fired. Because part of the job is making sure everyone knows the results are valid and accurate, and having voting machines connected to the Internet goes directly against "hey, you can see that no hacking is possible here". Doesn't matter how much the machine's manufacturer promises their machines are unhackable, the machines should not be connected to the Internet at all once they are actively being used for voting.

At this point, I'm ready to go back to paper ballots and a locked wooden box (kept in public view, and publicly verified to be empty before locking it up) myself. The simpler the solution, the better, is what I'm arriving at.
