@TheVigilante good question
Doctors : 1st world at least - If Elon's neural net implant works correctly, then as all body functions are monitored by the brain. The neural net will first attempt to cure a problem, when the cure is established that will be fed back into the central AI data base and be used to cure the same problem on any human/animal with he implant. But the scary part is, if you have the implant while still a fetus (which is possible) basically you will never need a doctor for the rest of your life. And you will never need a surgeon, if Elon's reset system also works with the neural implant then all thoughts will be translated into code. And if you hare injured/killed it will be easier just to make a clone (the neural net has your full DNA coding) and restore the neural implant data from a backup. Which of course touches on the the theory that we are a brain in a bathtub replaying an old memory.
Lawyers : I dont know, I assume that if you have every law and every verdict of a prosecution or transaction etc ever recorded, the AI will use that to make a determination of guilt or adjudication of argument?
Ship/Aircraft Captains : That's nothing new , most ships are piloted via computer/GPS and Radar. In fact the large freighters use a wind and current algorithm that can actually save fuel and speed up the journey.
Aircraft even commercial couriers like UPS have been using pilot-less freight aircraft between their private airports in the US. Pilot error is the number one cause of accidents in aviation, so AI could decrease fatalities.
Actors : I think this comes from the idea that AI could produce films that look like real people and places but are in fact just generated special effects. The Japaneses are trialing computer simulated manga and voices asking the audience which were real actors voices and which were not. As for theater performances, AI generated again but using holograms.
We have to accept that as a species we have continuously evolved. The merging of AI and humans is inevitable, not just for our mental and physical development. But because it will become essential for our very survival as a race.
