Compared to a self-driving car system, they are trivial. Your assertion that "they have been at the cutting edge of systems automation for decades" kind of indicates that - this stuff is simple enough to make that it was feasible to do even that long ago. Trivial is good mind you because it actually works, and works reliably. The same is not yet clear of self-driving cars.
