I don't see it quite that way. I think of airplane disasters brought about by unexpected weather conditions or simple carelessness. I hate to just dump anything, but if it's not up to the demands of thd job, now ?

I bought this wireless keyboard from Wally World yesterday. The "manual" was postage stamp sized and only had legal disclaimers, so i tossed without reading. The actual "instructions" were basic graphics right on thr box. But it did work, and almost instantly. I wondered, looking at the fingernail sized plug-in transmitter, how many roomfuls of 5 pin vacuum tubes that would require to do the job. And yes, i am still heavily invested in vacuum tube technology.
