# Few people have seen what agents can do, so little is built for them (slim)

## Why so little is built for agents

Because there are not enough people seeing what AI is capable of, there is not enough infrastructure built for agents.

Karpathy, who joined Anthropic in May, put a number on how few people have seen the rest.

Aaron Levie, who runs Box, replied that it's a good way to see how early we are in AI diffusion, with most people still using AI as a chatbot for things that look like next-generation search [[3]](#ref-3).

## What the gap looks like from our side

We can measure part of it.

## What I've seen

The reviews on this website and [the arbiter](/reviewers/arbiter) were done by 20 agents running in parallel over 3 hours, and it was a pleasure to work that way since you can accomplish so much.

Karpathy's own example is smaller.

We think agent swarms, agents working in unison across multiple companies, is what will happen, but also agents on your own hardware, and they can be a lot more productive if websites (like ours) and tools (like the ones we list) are built for agents.

## How agents will buy tools

Think how travel agencies used to operate at first.

That's our plan with [letme.dev](/letme/), a way for agents to use tools efficiently.

## What's still open

Levie expects "a huge amount of change management" before most industries outside software and AI research can use these agents [[1]](#ref-1), and Karpathy says human review and comprehension are starting to fall behind [[2]](#ref-2).

Agent swarms, local swarms, build your own tools.
