San Francisco’s tech community has embraced an unusual Friday night entertainment: humanoid robot boxing matches that draw hundreds of spectators to underground venues. The AI boom has fueled a broader resurgence of live events in the city, with tech workers seeking memorable experiences beyond traditional networking gatherings as a way to connect and decompress from work.
The big picture: San Francisco’s cultural scene is experiencing a renaissance driven by the AI boom, with nearly 2,000 live events held last month—nearly double from a year ago—and AI-focused events rising more than four times to 578, according to Luma, an event platform.
What you should know: Ultimate Fighting Bots launched in July as a monthly robot boxing event featuring $30,000-$60,000 humanoid robots from Chinese companies Unitree Robotics and Booster Robotics.
- The robots, about the size of third graders, are controlled by humans using video game controllers and given backstories, names, and costumes.
- Characters include “Googlord” (a Google intern with a pinwheel hat) and “Peuter Steel” (a Peter Thiel parody wearing a CEO chain necklace).
- Tickets cost $100 and are difficult to obtain, with the next match scheduled for September 27.
Why this matters: Tech workers are actively seeking community and unconventional experiences that feel uniquely San Francisco, moving beyond traditional professional networking.
- “If techies only get one day and from 9 p.m. to 11 p.m. to go out and do something, they want to do something weird and special that feels like it could only happen in SF,” said Josh Constine, a venture partner at SignalFire, a venture capital firm.
The broader trend: Beyond robot fights, San Francisco’s tech scene has embraced eclectic events including Taser knife combat (with rubber blades), AI-judged “performative male contests,” and AI-themed trivia nights.
- At one trivia night, SignalFire rented a larger venue after more than 600 people expressed interest, though only half were approved to attend.
- Events often take place near major tech offices, with one trivia night held blocks from OpenAI’s headquarters.
What they’re saying: Event organizers see this as part of San Francisco’s cyclical nature of tech-driven cultural movements.
- “It was honestly really surreal that this is happening in 2025. It felt like something that should be happening in like 2040,” said Jonathan Moon, CEO of Budbreak, a vineyard robotics startup.
- “This is peak SF,” said Carter Crouch, a former Amazon data analyst who traveled from Los Angeles specifically for the robot fights.
- Steve Jang of Kindred Ventures, an investment firm, noted that 30 years ago during the dot-com boom, friends gathered to watch primitive robot fights in the same city, and now “it just rhymes with everything that the city’s been about.”

DOE fusion roadmap targets 2030s commercial deployment as AI drives $9B investment
The Department of Energy has released a new roadmap targeting commercial-scale fusion power deployment by the mid-2030s, though the plan lacks specific funding commitments and relies on scientific breakthroughs that have eluded researchers for decades. The strategy emphasizes public-private partnerships and positions AI as both a research tool and motivation for developing fusion energy to meet data centers' growing electricity demands. The big picture: The DOE's roadmap aims to "deliver the public infrastructure that supports the fusion private sector scale up in the 2030s," but acknowledges it cannot commit to specific funding levels and remains subject to Congressional appropriations.
