In my experience, I would say yes. In the past, we were always pressed for time: we would start writing code and figuring things out as we went along. We tried not to jump straight into code, but the exploratory phase was hard and a lot of things were left out.

Now, the bottleneck is no longer the code. We spend that time thinking about the solution, how to deliver value, and how to plan for it.

I notice this most during team working sessions. Previously, there was always a moment when someone would say, "Hold on, let me note this down" and either the conversation went on without them and they lost the thread, or everyone else had to wait. Now, those sessions are just about discussion and exploration: the AI takes the notes, better than any of us. You can focus on thinking.
