Ah, that answer to it all, “A.I.”
Talking about this thread to one of my offspring who has done just a bit of work and research involving “AI” (ground road traffic environment, traffic signalling, traffic flow decision making, that sort of thing ) her view was that the capabilities of AI are frequently overstated. It’s improving, sure, but still “clunky” ....but neverthless sold as the answer to everything by the enthutiasts.
In her VHO truely pilotless/ AI driven routine commercial flight is still multiple decades away.
