I feel the same way. Thankfully there are still obvious signs in case of using LLMs, but it is not always so obvious. I think we may be better off assuming X is fake, and go from there. Sad but what could we do? There are websites that tell you (with a %) whether or not something has been written by an LLM. Unfortunately, however, some of my writings come out false positive. We may need to do improvements on this front, and I believe we will.
