Near the corner of Sixth and Market streets in downtown San Francisco, Frontier Tower has become a 15-story haven for the wildest and weirdest thinkers in technology. Floor 11 is full of longevity and health tech enthusiasts. The crypto folks are a floor above, with a lounge full of expensive furniture. AI is on floor 9. And the big event there this weekend is down on floor 8, where a group of biohackers hope to hot-wire the nervous systems of two live lobsters and control their bodies via remote control, one operated by a person, another by an AI agent.

“Worst-case scenario, we’ll have a good dinner,” said Elliot Roth, who is co-hosting the event and runs an 80-member biology and neurotech community on the floor, complete with a lab stocked with equipment like deep freezers, centrifuges and polymerase chain reaction workstations for DNA study.

Show up at Frontier Tower enough, and it quickly begins to feel like the type of place that could only exist in San Francisco, where there are seemingly endless numbers of people who will enjoy playing mad scientist with cyborg crustaceans on a Saturday night. The thinking of the building’s owners is more conventional: They’re hungry to expand. They’ve already opened a hotel for Frontier Tower members, and next they want to export the concept behind their thriving co-working and events space in SoMa to locations around the globe.
