Security of the data stream can be done very easily. Just because a few companies fail doesn’t mean everything with a computer is instantly hacked. This ends piracy, they can’t be taken physically and they’ll make the computer secure, heck the computer ALREADY is secure, they’re mostly operated by computer now.
Bad ole DOS is still possible, jam the transmissions.
Nothing’s perfect of course and it might be possible to get it very good by means of spread spectrum. But it’s going to be a people problem. Do people want pilotless craft among piloted ones? If you are piloting another craft, how do you signal a sudden problem to the controllers of the pilotless craft?
I understand that, but claiming that this ends piracy is just as silly as the folks who claimed the Titanic was unsinkable by design.
To say that this ends piracy is a bit amusing. There has always been the lure of profit in piracy and pirates have had a knack for continuing to thrive over the centuries.
