why are all electronics still binary? i understand how and why it works, but i dont understand why there hasnt been any transistors with more than just 1 and 0s. the way i understand it, the advancement of most technology is based on how many transistors we can cram into one physical area. well what if we had transistors that could be off, on, partially off, partially on, etc. instead of 0v pulse and 5v pulse you could have more exact pulses in between and so on. i know about memsistors but that is a bit different unless i am mistaken. could someone explain why there have been no advancements in the sense i am speaking of?
