First time working with someone who habitually uses LLMs. After respectfully requesting to not get pasted pages of output in chat conversation, they started copy-pasting selected passages in response to the things I hand-write. I notice increasingly that the human is just copy-pasting LLM output back and forth instead of thinking for themselves and maybe noticing that half the time the content is obvious and the other half irrelevant. Making progress this way is like walking through molasses.
seism0saurusI offen get request from a coworker who obviously let a llm write for him. I just read what he wants and ignore everything else. When I put a lot of smileys and useless Unicode chars in my answer. Often it takes more time to do that then the actual work. But a little bit if sabotage is required when handling people with ai. Sometimes in weiten dear Claude instead his name. He never complained.
