World models will also likely give rise to not just a single game, but an entire new category of generative world experiences. You could have a horror experience where you’re hiding from generated monsters, or a D&D experience where you’re roaming an infinite fantasy world with friends.
While the west coast, Patagonia-wearing VCs and the east coast, PE suits used to live in different universes… In 2026 with AI, I believe, those worlds converge.

Right now, most AI tools are built for one human + one model in a private workspace. ChatGPT, Cursor, Claude. Incredibly powerful, but currently optimized for individuals. The impact is massive: drafts, code, specs, campaigns, workflows. But almost none of it is shared, aligned, or contextualized across a team.
Say you need 50 qualified sales meetings. Instead of buying another AI tool, you post a bounty: “$500 per meeting booked.” AI agents compete. Whoever performs best gets paid. We already do this with bug bounties, Kaggle, hackathons. Why not for AI agents going after real business outcomes?
Picture an institution where courses, advising, research collaboration, and even building operations continuously adapt based on data feedback loops. Schedules optimize themselves. Reading lists evolve nightly and rewrite themselves as new research appears. Learning paths shift in real time to meet each student’s pace and context.
For over two centuries, our world has been shaped by one idea: economies of scale. This mindset delivered extraordinary progress: affordable/accessible nutrition, reliable housing, global transportation (and the accompanying shrinking of supply lines and cultural divides), and more. But in 2026, I believe this paradigm flips.
Ambition breeds ambition, and society needs ways to get the smartest and hungriest young people in a single room together. Residencies are one of the cheapest and most effective ways to create this clustering / cohesion—the expansion of solo founding / building only heightens the need for cohesive communities
The word on the street is that the kids don’t read anymore. Everybody overdosed on YouTube Shorts and Bang energy drinks and forgot how to flip a page. So the story goes. But something strange is starting to happen. Startups are talking about wanting to hire “storytellers.”
The best movie/game/book recos I’ve gotten came from word of mouth or short-form videos, which led me to YouTube, which I then consumed while then going to Reddit to discuss. As cliche as it sounds, can AI solve this? An ‘agent of my tastes’ recording the things i consume and suggesting the most relevant pieces of media worth spending my time on.
This past year, I’ve had a front-row seat watching teams at a16z speedrun build AI agent companies across legal, logistics, manufacturing, and other complex, operational domains. What’s striking isn’t just how capable these agents are, it’s that they already take responsibility for outcomes, not just information. Seeing that up close has changed how I think about e-commerce.
I’ve spent much of my career around marketplaces and the classic playbook was powerful: bring fragmented supply online, aggregate it in one place, make it easy to search, and reduce friction at checkout.
Back in 2010, Ben Horowitz said some startups should go fat—build the full stack, own distribution, and move fast—while Fred Wilson preached lean. Fifteen years later, the debate’s settled: in the AI era, fat startups win. A fat startup ships outcomes, not features. It bundles software, data, hardware, and human ops into one integrated product that actually gets the job done.
Predictive health could transform the health insurance industry from a cost of treatment model to a cost of prevention model. Smart cities powered by AI that integrates traffic, utilities, school and safety data to create better urban environments. Natural disaster prediction and remediation planning to save lives and trillions of dollars.
AI is doing the grunt work so we can finally master human work. This speed of change is pushing us toward what truly matters: self mastery. We can’t control the external, but we can strengthen our internal operating systems by using tools that scale emotional intelligence, foster faith, and bridge the isolation AI risks creating.
I’m especially excited about products that use AI to make previously expensive services cheaper and more accessible, sometimes using human-in-the-loop to start. This includes things like AI travel agents, personal assistants, matchmakers, therapists, tutors, and more.
