I don't see why a digital counting machine which is kept completely offline and is transported physically cannot be used, specially if we can verify it's counting functions by randomly verifying a few of those machines (also keep paper ballots, just use the machine to count ballots), or statistics, and use an external randomization/derandomization module.
But a non-hacked vote tabulating machine will still do the job better than non-hacked humans.
Add a high enough percentage of random hand audits of the machine but counts to ensure they're functioning correctly, and you should get a reasonably high confidence that you have the most accurate count.
Defies the purpose of electronic machines completely. Why use machines + lots of auditors, when just more counters (worth less than auditors) could do the same job, with a much higher cost to corrupt?...
As if the totally secure communications over Internet problem had been solved. Why are we seeing SO MANY issues with TLS, VPNs, hardcoded root passwords everywhere, ssh issues even!...
