Re: self-driving trucks... I've been hearing predictions of how technology was gonna change this, that, or the other thing, since roughly around the tail end of the Apollo program. I've been working in computers since the days of 8-bit CP/M (of which 16-bit MS-DOS was a pirated clone). I've been building/administering internet nodes since 1990, when folks were still (incorrectly) referring to it as ARPAnet. I've been working with web servers since roughly 1992-1993. Did my first $100M revenues eCommerce system in the mid-late 1990's. My first computer engineering professor was a former member of the Manhattan Project, who built...[...redacted...]. I've been hearing so damn many predictions about how this or that technology was gonna change the rules. With all due respect, I call bullshit. Airplanes can fly themselves, as long as conditions fall within those projected by the engineers. The hundreds of bodies racked up in just two 737MAX crashes show the folly of engineering managers who think their analysis superlative to the skills of truck drivers or airplane pilots. Engineers tried to stop the 737MAX fiasco, and the Space Shuttle Challenger fiasco, but in both cases were overruled by engineering managers.
I think this is why we use the phrase, "X is the best thing since sliced bread." Nothing has improved man's lot without any downside since sliced bread. Except, of course, for Tamara Taylor.
