Interacting with ChatGPT (or any LLM chatbot) without a goal is akin to buying a tool you have no projects for. And just as a hammer can't provide plans for a grotto, chatbots can't really talk me into there being a reason to chat.
I'd also be curious to train a local model on my past work, but it feels like it might keep my attention for a bit and then I'd run out of transformative ideas. At this point, I know this is the inescapable future, but I'm swinging wildly between thinking we're going to find huge advantages and, well, apologist item descriptions.
