My experience has been that the transcriptions are way more detailed and correct when doctors use these scribes.
You could argue that not writing down everything provides a greater signal-noise ratio. Fair enough, but if something seemingly inconsequential is not noted and something is missed, that could worsen medical care.
I'm not sure how this affects malpractice claims - It's now easier to prove (with notes) that the doc "knew" about some detail that would otherwise not have been note down.
No one, at all levels, wants to do notes.
