Half the ultra wealthy guys in Silicon Valley are doing this. Adrenochrome, blood transfusions from prime donors, whatever will help them live to 120. Hollywood and hedge fund guys. Elon Musk for sure. Peter Theil I believe. Sergy google guy and many others.
There was a recent longevity conference hosted by xxx in Austin Texas. 5000 attended.

The Dave Asprey event you are thinking of is the BEYOND Biohacking Conference (formerly known simply as the Annual Biohacking Conference), which just held its massive gathering at the Fairmont Austin from May 27–29, 2026.
True to your numbers, the event draws 4,000 to 5,000 attendees and is the longest-running longevity and human-performance event in the world.
The biggest takeaways, tech debuts, and details from the Austin event include:
🧠 The Big Theme: “Health Optimization is Dead”
Dave Asprey made waves at this specific event by declaring that the old mindset of health optimization is a trap because it forces people to ration a limited amount of energy. His new focus for the conference was energy expansion and resilience—building a body that creates more energy so you don’t have to meticulously score and micromanage your sleep, macros, and stress.
🔬 The Tech Playground (150+ Exhibitors)
The conference floor at the Fairmont was basically a futuristic playground for advanced recovery and longevity tools:
Stem Cell Mobilization: Handled by title sponsor STEMREGEN®, focusing on natural cellular repair.
Quantum-Charged Nootropics: The buzziest tech on the floor was a supplement called IgniCognition by Ignition, which claimed massive cognitive and memory retention boosts using molecular tech developed near CERN.
The Essentials: Massive setups for full-body diagnostics, live liver scanning, hyperbaric oxygen chambers (via OxyHealth), neurofeedback, and BrainTap mental fitness tech.
Hacktivations: Live, hands-on group sessions for heart-rate variability (HRV) training, sound baths, and intensive guided breathwork.
🎙️ The Heavy-Hitter Speakers
The main stage focused heavily on merging hard biology with emotional grounding and nervous system regulation:
Jay Shetty: The former monk and podcast giant, who focused on purpose-driven living as the ultimate nervous system regulator.
Dr. Gabrielle Lyon: Breaking down “muscle-centric medicine” and metabolic longevity.
Arthur Brooks: A Harvard happiness scientist lecturing on the literal biology of joy.
The Afterparty: To close things out, world-famous DJ Steve Aoki spun a late-night set for the attendees.
(Note: If you are looking to go to his next Austin event, he is also hosting BEYOND Wonderland at the Omni Barton Creek Resort this October 13–14, 2026, which shifts the focus specifically toward psychedelic science, plant medicine, and consciousness tech.)
They still can’t control things like the Kreb’s cycle or the law of unintended consequences
