The most important feature of public elections is trust. Efficiency is one of the least important feature.
When we moved away from paper voting with public oversight of counting to electronic voting we significantly deteriorated trust, we made it significantly easier for a hostile government to fake votes, all for marginal improvements in efficiency which don't actually matter.
Moving to internet voting will further deteriorate the election process, and could move us to a place where we completely lose control and trust of the election process.
