Indeed, at 3 pieces per second (I don't have a good sense of how fast good tetris players play, but I've seen some videos and it looks like they can average more than one a second), it's 10 hours of constant play.
Playing at such a speed for 10 hours is kind of insane. Playing it without error is not human.
