Scratching the Surface

What smarter machines reveal about the mind.

We don’t understand the brain well enough.

Unlike what the AI hypemachine would have us believe, the mind is not a pure reasoning engine. Emotions, intuition, and feelings sit inside almost every decision we make. We, humans, are not entirely rational beings. Most of the choices that shape our life are not the result of pure logical thinking. They come from the whole system working together. Sometimes reasoning dominates. Sometimes intuition lights the path.

We are watching AI models get extremely good at the reasoning part. Stronger, faster, more capable at pure inference. People talk about them replacing knowledge work or replacing the entire workforce.

I think the opposite may happen. The current assumption is that better machine reasoning will make models think like humans, that pure logic is the pathway to a “superbrain.” It may do the reverse. AI's continuous improvement in this dimension may actually make us see (and perhaps appreciate?) the unexplainable blobs of emotion that make us human more clearly.

As these models keep getting better, they will expose how little we still know about whatever we call the mind or the brain.

We’re only scratching the surface.

AboutMe

Hi, I'm Raisul Chowdhury, a data scientist and product builder in San Francisco.

I grew up in Dhaka, moved to Toronto in my twenties, did an MBA at Kellogg, and have been in California with my wife and son ever since. Before Google, I helped grow StackAdapt from 70 to 1,000 people. And way before that, product and growth across digital platforms in emerging markets.

My titles changed over time, but the work I do stayed the same: understand the user, find the gap, ship it, learn, ship again.

These days I build AI products at Google and write about where the machines end and we begin. The bet underneath: AI that makes the person using it sharper, not smaller. I don't know if it's right yet. I'm building toward it.

When I'm not working, I'm usually at the park with my son, making waffles, or sitting with music and chai thinking about what comes next.
