As a computer scientist, this is one of those statements that kind of bugs me.
A little while back, I had to listen to a 2 hour talk about how electronic voting absolutely should not be used because it's not secure. He rattled off video after video of various techniques that have been found to hack or tamper with any number of devices in the electoral process. The moral of the story was that we should continue using paper ballots, and specifically keep a system that has a physical paper trail.
But like any argument related to politics, it builds a conclusion based on evidence of one thing without looking at the other side.
Paper ballots are very easy to tamper with, and despite every state using some form of electronic voting, the most significant amount of fraud happens at the paper level, not the electronic. The modern equivalent of "stuffing the ballot box," poll workers deliberately tallying incorrectly, losing ballots so they can't be counted, these all happen and so much more. Paper voting isn't secure in the tiniest bit, yet we insist that electronic voting must be 100% secure or it should not be used. Just that good old classic "fear of the new and unknown."
