There is nothing special about mechanical that makes it inherently more reliable than electronics, and vice-versa . I’ll give you an automotive example- I prefer manual transmission. Probably for some of the same irrational reasons that you don’t like electronics; I just like to be in direct control of the car. But is it some panacea beyond that? Over the years I have had a couple complete failures. Master cylinder failed and I couldn’t shift. the sifter mechanism physically got stuck in gear. Meanwhile the wife is happily driving along with her auto transmission, and has some pretty nifty paddle shifters in her current car.
Actually I am very knowledgeable in electronics. It is not that I don’t like things electronic. It is that I am smart enough to know that somethings are too important to leave totally in the hands of electronics and software that are subject to design flaw and just plain component failure. I have no problem with the electronics being there. Just put an over ride on it for in case it fails. That is the way it should be when your life could be on the line.
