Maybe it is.
Just like hand made items are popular for their imperfections.
And because hands can still make things that machines cannot.

An awful lot of stuff in the "hand made" aesthetic are made by machine and factory too, and I suspect a similar thing will happen to any popular writing aesthetic that attempts to avoid being automated away.
Personally, I'll just continue to use my own voice. I try to correct spelling and grammar mistakes, and proof-read my writing before posting.
It's not perfect, and my writing can at times be idiosyncratic, but it's my voice and it's all I've got left.
But don't be mistaken in thinking that those mistakes make it better, it just makes it mine.
