@Viss This is a cool invention. But it also highlights something kind of alarming.

At a couple points in the video. They show pictures of the screen and there are clear typos. Sometimes it's "hoep" sometimes it's "ou" instead of "you", sometimes it's the capitalization.

And while the machine is not perfect It is still a machine. Those letters are supposed to be hitting in order. Like, I don't expect a typical human to be more accurate than the machine.

So what's wrong with the keyboard?

Person built a literal keyboard music box and it's not even playing the song notes in order?
