I believe a good doctor, properly focused, will outperform an AI. AI are also still prone to hallucinations, which is extremely bad in medicine. Where they win is against a tired, overworked doctor with too much on his plate.
Where it is useful is as a supplement. An AI can put a lot of seemingly innocuous information together to spot more unusual problems. Rarer conditions can be missed, particularly if they share symptoms with more common problems. An AI that can flag possibilities for the doctor to investigate would be extremely useful.
An AI diagnostic system is a tool for doctors to use, not a replacement.
We have so many accents, even within England, let alone the empire, that we had to invent a reference accent. Queens English is what the BBC used for a long time. It was intended that all ‘cultured’ workers should be able to converse in it. This meant the upper class could travel anywhere and not have to deal with local accents, when ordering the servants about.
It’s still quite useful, since it is intended to be easily comprehensible to all English speakers. Downside is that it makes you sound like a posh twat.
