The pragmatic in me understands this. Pinball balls don’t get stuck often with good maintenance, and outside of gaming (and music!), keyboards don’t need flawless detection of many different keys being pressed.
Yet, it’s still disappointing, this indolence of machines, the fact that it’s all so simple, stupid, and unnervingly close to guesswork when it should be absolute certainty.
But in those limitations of machines there is also a fun opportunity. One of the most mind-blowing discoveries of my childhood was when my father showed me you can remove the glass shielding the pinball playfield, and play the game without the ball at all. Instead, you could use a screwdriver, a pen, or – if you are brave enough – even your fingers (brave because the angry solenoids kicking the ball around are strong and can actually hurt you!).
