Given how many people can't seem to distinguish between LLM output and an actual human, and how many actual humans I've interacted with who I only later realised were actually human, I think it won't be long before humans who can distinguish and write distinctively are a minority.

You can do this with shortwave: https://www.shortwave.com/blog/introducing-ghostwriter-ai-wr...

On thing that is interesting is that they allow you to add additional prompt, because sometimes you don’t want an email to actually sound like you but it to sound like the writer you want to be (leveling up so to speak)

It’s already a thing now

It's already possible. Upload your text and one you want it to look like, then instruct chatGPT4o to rewrite the first text so it follows the word structure, form and layout of the second one.

Then run the whole lot through Grammarly in academic mode to get rid of flowery words and tortuous structures.

Too many academic papers try to impress with complex language rather than explaining what needs to be explained in a pithy and succinct manner.

I can confirm this works.
