Because we don't have to wait for working technology.
We could import it from India, which voting machines that manage to tabulate votes for the world's largest democracy in a few hours. They're much simpler and more robust than for example Diebold's machines. Here's a good case for overseas outsourcing!
Even simpler, we could do what we did for many years: use paper ballots.
Don’t let ‘em count the votes with some man-made machine
The only way to count 'em right is to count 'em all by hand.
Mark your ballots on a piece of paper and count ‘em all by hand.

We have the technology.
What kind of risk management is it to continue using some other technology that is known to be massively broken, when what is at risk is the entire political system?
Beyond voting techniques, maybe we should also pay attention to content:
I ain’t a gonna vote for man nor beast who’s full of lies and fear,
on that day on that great election day.
