It's what I thought too. Would I be able to tell the difference? That thought really scares me. What if in not so distant future whole threads, comments included, are LLM generated?
We are losing touch (ppl like you and me), and I feel it coming. That is not the first article on the web, that I quit reading in disgust, thinking 'FUCK, what if I'm reading GPT4 babble right now?'
We will need a way to tell 100%.
