A lot of games didn’t work properly if turbo mode was engaged. They would run unplayably fast, have crazy game breaking visual glitches, or just crash. A few of my games had a splash screen reminding the user to turn off turbo mode. The turbo button was mainly there to speed up processing for mundane tasks like spreadsheets or for compiling code.
“Hanging chads” on paper ballots helped Bush swing/steal the election from Gore. Paper ballots have a lot of problems too. At least in California every vote on an electronic voting machine generates a paper ballot.
