The fact that it takes as long as it does in the US and there is still a fear that it's not secure or that it's suspicious--no matter how wrong that fear may be--is a problem. And it's not a "dumb normies need more education about statistics" problem. It's a problem created by forcing a "solution" that is unnecessary (paper ballots, counted by hand work fine) and unnecessarily complicated.
If people dont understand that printed paper ballots cant be changed by an air gapped electronic system you wont gain their trust anyway.
Electronic voting is unnecessary and unnecessarily complicated. Your response to this is basically “they’re too dumb to to understand and so don’t matter anyway.”
"Your response to this is basically “they’re too dumb to to understand and so don’t matter anyway.”" No, my response is that a pure paper ballot system wont change a thing and would just shift the conspiracy theories to other parts of the system.
So the issue isn't "electronic voting" vs. "paper ballots".
