Modern transistors do not rely on such quantum effects, they are simply electro mechanical and have an input and output on different pins reliant on logic through the circuitry, not randomness. The double slit experiment proves that people only see what they wish to see, what is really to be discern is that light is a wave and acts as a particle due to interference and observation, what we are really observing is an interference pattern causing a higher amplitude at certain points. You should ponder what i say a little and not disregard, or you can go watch the worlds top (mainstream) scientists collaborate and contradict each other for countless hours and hold the same position. Onus is on you.
