Allison Duettmann — Why We Don't Have to Die: Cryonics, Uploading, and Existential Hope

Why cryonics and mind emulation could mean we don't have to die, how nanotech could rebuild the physical world, and the case for Existential Hope — picturing futures worth building.

New episode with Allison Duettmann, the CEO of the Foresight Institute.

Foresight has spent the past 40 years backing frontier science too early or too interdisciplinary for legacy institutions. It has helped inspire and organize 10,000+ scientists, technologists, philanthropists, investors, students, thinkers, pioneers, and dreamers — including the early-2000s space community where Elon Musk and Steve Jurvetson discussed the importance of commercial space and reusable rockets. Foresight's Feynman Prize went to Fraser Stoddart and David Baker 9 and 20 years before each won a Nobel. Today, Foresight is one of the main communities where neurotech pioneers gather and explore the frontiers of BCI, connectomics, simulations, and uploading.

Allison also founded the Existential Hope movement, rooted in the conviction that we must imagine flourishing futures — in the tradition of ambitious science and sci-fi — as a precondition for building them. She is one of the best people thinking deeply about the future, coordinating humanity to imagine and achieve good outcomes, and working to accelerate the technologies and adoption that will get us there.

We go deep into all of that in this episode: how neurotech could let us connect far more directly than language allows; how BCIs are meaningfully improving people's lives today; why connectomics and whole-brain emulation can keep humans compatible with superintelligent AI; why uploading could give us a path to exploring ourselves and living vastly richer, more fulfilling lives than a single ~80-year narrative arc allows; the possibility of living billions of years; and how nanotechnology could reshape the physical world, address our sustainability and energy challenges, and build the infrastructure to lift us off planet and explore the universe.

This is a ton, and goes to show how deeply and broadly Allison thinks. She explains things clearly and bridges huge divides with care, vision, and rigor. Hope you enjoy!
