Very clever Griff. There are alarming differences though. The computer kill rate is almost genocidal. Trains are just boiling kettles, or mechanical behemoths, its not hard to control, fix, or predict. Computers are a new horizon, to pretend like the Boeing engineers, that it AI is safe is nonsense.
You are right though that we need to progress, but not at the expense of airliners smashing into the ground nose first. The pace of trust and progress is too quick.

Steven Hawking etc says that mankind wiill be under threat from AI. Whether or not thats true or not is not known until we understand more about consciousness. I doubt if consciousness can exist in a computer, no matter how advanced, but then again who knows. If consciousness can exist in a computer, then god help us all.

There is a theory that i hold to is that consciousness cannot be created, that all things are alive to some extent or another. If that is the case, computers are alive.
