Apart from the other points that have been raised: basically every recent report about Ukrainian troops has gotten a bit in it along the lines of “they’re exhausted and have taken heavy losses, but are in good spirits and willing to fight on”.
Especially if you read what individual soldiers are saying, I get the feeling that this war would not end, even if support to Ukraine where to vanish completely (good luck convincing Poland, the Baltics and Nordics). You’d just get Afghanistan, but the invaders are openly genocidal and don’t give a fuck about civilians at the best of times.
OK, cool now teach your family that calls their web browser “The internet” enough computer science to adequately understand and audit this proposed open system and convince themselves that their votes are counted in a fair, verifiable and secret manner. Also that the implementation does not have obvious side channels and what is actually running is built from the published source code.
Like, If I was part of some shady powerful elite I’d love a fully automated setup. Most people will not be able to check the system deeper than “phone displays green check mark” without an unreasonable time investment.
On the other hand, “room full of people opens box full of papers and counts them while verifying each other” is intuitive enough for almost anyone to grasp and gain confidence in.
