I had a similar experience. Just chatting about stuff, shooting ideas and concepts back and forth with the AI is quite stimulating. I get to be an obnoxious help vampire without draining other humans of their patience and motivation. It's like having a developer friend with infinite patience to chat with.
In terms of productivity it's having something of a mixed effect. It gives me very clear ideas and direction but at the same time everything just feels done afterwards. All that's left is actually executing the tasks which is... Boring.
I'm not sure I trust ChatGPT to do it for me like an agent. The examples it gives me are never quite right. It's probably a lot better at generating frontend javascript code than programming language interpreter code.
