Age of Fakes: Brian Chesky Bets on Reality in the World of Neural Networks

While the industry competes over whose language model hallucinates better, Brian Chesky has decided to remind us of the existence of the physical world. The founder of Airbnb put forth a thesis that at first glance seems obvious, but upon closer examination reveals the main pain point of Silicon Valley. In a world oversaturated with synthetic content, authenticity becomes the most valuable currency. The irony of the situation lies in the fact that tech giants spent years teaching us to trust the screen, and now they're trying to save us from what's displayed on that very screen.

Chesky isn't just philosophizing about "reality." For his business, the question of verifying reality is a matter of life and death. Airbnb spent years building a trust system between strangers, relying on reviews and photographs. But what happens when a neural network can create a perfect interior of a non-existent villa on the Côte d'Azur in a second? Or when a host profile turns out to be a flawlessly generated face that was never touched by sunlight? The trust that was built over a decade can crumble in a couple of months if users start doubting the reality of what they're booking.

The technical implementation of this protection—that's where the real problem lies. Brian Chesky acknowledges that we don't yet have a universal "truth detector." We've learned to generate lies at industrial scale, but we haven't created tools to automatically expose them. Currently, Airbnb has to use complex behavioral analysis algorithms and cross-checking of data to filter out fakes. However, this is a battle between armor and artillery, where the projectile (AI) becomes cheaper all the time, while the armor (verification) gets more expensive and heavier.

Many call Chesky a visionary precisely because he predicted the opposite swing of the pendulum. After a decade of digitalization and escape into the metaverse, people are starting to hunger for physical experience. We want to touch things, see living people, and sleep in real beds. AI paradoxically pushes us back offline, because the online world is becoming too suspicious a place. If the internet used to be a window to the world, now it increasingly resembles a room with distorted mirrors, where behind every pixel an algorithm might be hiding.

The problem of verification extends far beyond housing rentals. This is a challenge for the entire sharing economy and social communications. If Airbnb solves the problem of confirming reality on a scale of millions of objects, the company will create a standard that will cost more than all of its current assets. This will be infrastructure of trust in a world where you can't trust anyone. Chesky understands: the winner will not be the one who offers the best service, but the one who guarantees that this service actually exists in the material universe.

The key point: Will Airbnb become the "ministry of truth" for the physical world, or will deepfakes make online booking too risky an attraction?
