Yet many rich democracies have been using electronic voting without issue. There’s an entire field of science and engineering for securing digital democracy, don’t take a single YouTuber as your source (ftr, I like Tom Scott’s videos too)
What countries except of Estonia actively using digital voting?
Russia is, albeit I wouldn't exactly call these elections democratic...
And on top of that there was massive fraud with votes due to re-voting option existing. Certainly Russia isn't a country that you want to take as example in anything related to democracy.
