It just means that you will have to evaluate prose on its own merits (aesthetic, logical, etc).

The main problem with LLM-assisted writing is that effort-to-write is now much lower than effort-to-read -- the LLM-prose-style is simply an imperfection that can sometimes help the reader bail on a piece (and there might be false-positives).

Most people are already biased against reading long pieces, and seem to skim them more often than not. These people are _probably_ a little worse off than before, but they are not paying full-price for being hoodwinked. The people who end up paying full-price are probably going to become more sophisticated in how they choose what to read. I can't tell if this will be good/bad for publishers and/or advertisers.
