I have met multiple brilliant, very bright, and talented people (mathematicians, physicists, doctors) who excel at what they know and do, yet immensely struggle to spell, write, or both. There are also people who do not like to write (whatever the reason is).

GenAI has been a great boon for such a type of person as it dissolves their struggle – they convey the idea to the machine (however awful the scribe is) and GenAI handles the grammar and style.

Granted, it is different from «hey, GenAI pet, write me a blog post on XYZ».
