Also, I find it far more powerful for planning and solo brainstorming than for the coding. For every piece of code that it speeds up, it also means that much more code that is not baked into my head, so my debugging and conceptualization of the codebase is weaker. And that isn't even taking into account the need to check an AI's work.
But when I need to do something utterly unlike any of my previous work, instead of digging in for a day or two just to conceptualize a novel feature, I can get a plan of how to approach and architect the feature in a few minutes. And the quality doesn't really matter at that point - if it is good, I can run with it. If it is bad, it gives me a baseline to react to and make a better plan, which also speeds me up.
