Huh... You really dived into the deep research on the topic... :)

I remember my sister's final exam at the University where her topic was software that she made, which was "emulating' a doctor... It would run a series of questions about your symptoms, and in the end, give you the final "opinion" about your potential illness and give options how to treat it... That was almost 30 years ago... So, AI isn't really as new, as it looks like, but it has evolved into something much bigger...

Why this story? Well, I'm also stuck on your example of 3 professions, doctors, preachers, and lawyers... In my opinion, the first two are (at least should) act objectively, they could be easily replaced by AI... But, with lawyers, I'm not sure... Yes, they do some trivial stuff, like contracts, agreements, etc. and that could be replaced by AI... But, replacing them in the court, where they "pick" type of defense, "skip" parts that would harm their client, and do similar things, it's more tricky to implement into AI... Not impossible, but more tricky... And in the end, would that be ethical to do? Would that AI implementation bounce back and kick us in the ass?

Luckily, the AI development isn't finished and it will continue for a long time... In which direction, we will see... 😃
