Ultimately, is paper the gold standard we should stick to?
Nope. Come to India and watch how voting machines are used efficiently in almost all elections, from local bodies to Lok Sabha elections.
Efficient maybe, but trustworthy? How can you know that the voting machines are not rigged in any way? (The same goes for e.g. Brasil.)
No party has dominated elections in India over the years since the EVM has been introduced. The Election Commission is the autonomous authority responsible for conducting all elections in India and there has been no information of corruptions regarding them till now.
