AI lets a single person do what used to require a team. Learn a new domain in an afternoon. Have a personal tutor for any topic. Research, prototype, ship.

But none of it has made our brains magically faster.

We process information better with AI. It's a tutor, a rubber duck, a sparring partner that helps you reach understanding you'd struggle to get to alone. The tools are genuinely good at helping you think.

What they haven't done is close the gap entirely. The input bandwidth exploded. Our ability to absorb, connect, and retain all of it didn't scale to match. The rabbit hole got deeper and branched into a maze.

When I deep-dive into a new domain or framework, I hit the Dunning-Kruger peak in hours instead of weeks. That false summit where you feel like you understand something because you can talk about it fluently. One insightful session and you're ready to build. That confidence is the dangerous part. It used to take long enough to reach that point that you'd often self-correct along the way. Now you can arrive before lunch and start executing by the afternoon.

The discipline I've had to learn is stopping. Not because the tools are wrong, but because my brain hasn't finished sorting what the tools gave me. Step away. Think about something else. Let the back of your mind connect new ideas to things you already know, surface the contradictions you glossed over, separate what you understood from what you merely encountered. Then come back. That cycle is what cements understanding, and it doesn't happen at the speed of a context window.

You can follow any path further and faster than before. But speed through a maze isn't progress. Knowing when to stop and let the map form is what turns information into something you can build on.

This matters most in product work. Agents let you research a market, synthesise findings, and prototype solutions faster than any team could a few years ago. What they can't do is build empathy with the people you're solving for. Understanding a domain well enough to talk about it is not the same as understanding the people who live in it.

The most useful thing I've found AI good for in that context is getting me to the starting line faster. Enough fluency in a new field to ask informed questions of the people who've spent years there. Not to replace the conversation, but to earn it.

The speed is real. What you do with the pause after is what makes the difference.
