Every two years, America drags old, expensive, proprietary machines out of storage to perform the single most important technological task in a Democracy: count votes. And without fail, these machines break down in some districts, causing obscene waits and generally undermining faith in the democracy.

This year’s election follows that general trend: Voters in South Carolina are reporting machines that switched their votes after they’d inputted them, scanners are rejecting paper ballots in Missouri, and busted machines are causing long lines in Indiana. The issue is particularly bad in New York City, where several people told Motherboard they stood in line for four hours before voting because machines that scan paper ballots weren’t working at many polling sites.
