Advancements in Xenotransplantation

Josh Wolfe is a co-founder of Lux Capital, where he funds the kinds of ventures that change everything: think gene-edited pig organs and technology that lets you “record” smells. His approach? Relentless curiosity. He reads dozens of newspapers daily to identify patterns, always staying a few steps ahead. In this episode of The Generalist, Josh shares how his firm backs companies that don’t just predict the future, but create it.

In our conversation, we explore:

• The revolutionary development of genetically modified pig organs being transplanted into humans and what this means for the future of organ transplantation.

• The recent achievement of "teleporting smell" across space and why computers that can replicate scents will open up entirely new industries.

• Why Lux is investing in the search for real-life "X-Men" — genetic outliers in isolated populations whose DNA could lead to life-saving medical advancements.

• How Josh evaluates macro trends to make smarter micro investment decisions and why ignoring the big picture is a mistake.

• The three tech sectors that Josh believes will define the geopolitical balance in the decades ahead.

• How Josh stays current on macroeconomic trends.
