AI just crossed another line that sounds small but isn’t.

AI assistants are making phone calls, booking things, sending emails and interacting with businesses for us.

That matters because the first generation of generative AI was mostly conversational. We asked a question. It answered. We asked it to summarize something. It summarized it.

Now AI is increasingly moving from conversation to action.

For the first few years, we were asking:

“What can AI tell me?”

The more important question is becoming:

“What am I comfortable letting AI do for me?”

That’s a much bigger psychological shift.

There’s a difference between trusting AI to summarize a meeting and trusting it to call a restaurant and convincingly explain what you meant by “a quiet table, but not too quiet.”

AI Capability Is Becoming AI Authority

The more useful AI becomes, the more permissions we are going to give it.

Access to our calendars.

Our email.

Our business systems.

Eventually our money, travel plans, purchasing decisions and countless other pieces of our lives.

And once AI can act, mistakes become different.

A hallucinated paragraph is annoying.

A hallucinated action can become a real-world problem.

That doesn’t mean we should stop giving AI more agency. Quite the opposite.

I think AI agents are going to become incredibly useful.

But the systems that succeed won’t simply be the smartest ones.

They’ll be the ones we trust enough to actually use.

Trust May Become AI’s Killer Feature

For years, the AI industry has competed primarily on intelligence.

Who has the smartest model?

Who scores highest on the benchmark?

Who released something impressive this week?

Those questions still matter.

But another competitive advantage is emerging:

Can I confidently let this thing act on my behalf?

That requires reliability, transparency, sensible permissions and an ability for humans to understand—and sometimes undo—what the AI has done.

The killer feature of the next generation of AI may not be intelligence.

It may be trust.

And I’m not sure we’ve figured out yet exactly how much of it we’re ready to give away.
