>That said, if I don't use AI at all, since I pride myself on running a technical blog, not detecting technical errors would also be a problem. So it's a dilemma.

Is it? To err is human. Embrace the risk of technical errors and what/how we learn from them.

>The issue is that human writing is generally rougher. But if we insist on preserving only human writing, we end up having to define humanity's roughness as mere "barbarism."

Is it truly "barbarism", or is it just... human? What's wrong with writing being a bit "rough around the edges"?
