I would say that I think more "graphically" now. I would not necessarily say I think harder, but rather with less total cognitive load by thinking ahead.

What do I mean?

When I think about problems now, I still use first principles thinking. Then, I begin with a spatial map of ideas and concepts. How are these things related? Are there any patterns or gaps?

Before AI agents, I didn't have to think in terms of steps.

With AI agents, I can have them tackle each part of the graph simultaneously to arrive at a deliverable. Faster, and with more predictability.
