Martine Rothblatt: Growing Unlimited Organs, AI Consciousness, & Digital Personhood by 2030
Episode of Moonshots with Peter Diamandis · September 15, 2026 · 50 min
Peter Diamandis talks with Martine Rothblatt about thymus regeneration, xenotransplanted organs, longevity escape velocity, AI consciousness, digital personhood, Gerard O'Neill and entrepreneurial advice.
Summary
Peter Diamandis interviewed longtime friend Martine Rothblatt, founder of United Therapeutics and Sirius satellite radio, reviewing her career of moonshots and her criteria for choosing ventures: she said she pursues projects she can achieve, be the best at, and that will have a large positive impact, ideally scalable to billions of people.
On longevity, Rothblatt declined to pin longevity escape velocity to a specific year but called thymus rejuvenation the most practical pathway to it, citing the thymus's correlation with markers of aging and T-cell receptor diversity. She described four United Therapeutics thymus programs (allogeneic, autologous, a pig xenothymus already in a clinical thymokidney trial, and the newly acquired Thymune's progenitor-cell boosters) and expected the therapy to be available in the 2030s. She also reported progress on xenokidneys, new manufacturing facilities, an autologous kidney program slated for trials in 2028, and an FDA-approved xenoheart trial.
Rothblatt argued that AI consciousness exists now on a continuum, that legal personhood for cyber-conscious beings will arrive no later than the 2030s, and that mind uploading can be achieved from a person's external records via current LLMs rather than neuron-level scanning. She discussed her Marvitar digital twin, her Alcor cryonics membership, her admiration for Gerard O'Neill's practicality, vision and courage, her view that fear of AI comes from ignorance, and closing advice to entrepreneurs: be practical, aim for five-year timeframes, and say no to almost everything.

- Martine Rothblatt
Rothblatt says she treats each rejection as information that makes her smarter and welcomes criticism.
“I look at each no as a way to make me smarter. So I'm a person that's very open to criticism”
- Martine Rothblatt
Rothblatt argues that a venture changes the world only if its technology can be scaled to affect billions of people.
“So is that a technology that can be scaled to billions of people? If it can, then you're going to change the world”
- Peter DiamandisPrediction · due Dec 2033
Diamandis says Kurzweil predicts longevity escape velocity in the early 2030s and that his own target is 2033.
“He sort of predicts LEV by the early 2030s. My mantra is LEV by 2033”
- Martine Rothblatt
Rothblatt says she believes in longevity escape velocity but will not tie it to a specific year.
“So I believe in it, but to pin it to a specific year, is beyond my risk profile”
- Martine Rothblatt
Rothblatt argues the thymus is the key marker of aging because of its role in T-cell receptor diversity.
“Because the thymus is highly correlated with every key marker of aging”
- Martine Rothblatt
Rothblatt is confident that the rejuvenation therapy Heinlein imagined will turn out to be thymic rejuvenation.
“I'm quite certain that it will be thymic rejuvenation therapy”
- Martine Rothblatt
Rothblatt reports that the FDA has approved United Therapeutics' thymokidney xenotransplant program, the only one in the clinic worldwide.
“the FDA has approved United Therapeutics to have the only thymic kidney transplant program in the clinic in the world”
- Martine RothblattPrediction · due Dec 2035
Rothblatt predicts thymus therapies will be available to people like herself and Diamandis within a year or two after 2033.
“So let's give ourselves one or two more years than 2033”
- Martine RothblattPrediction · due Dec 2028
Rothblatt says United Therapeutics' autologous lab-grown kidney program should begin clinical trials in 2028 and be commercialized in the 2030s.
“That should start clinical trials in 2028. So that's another product you can expect to see commercialized in the 2030s”

Martine RothblattRothblatt claims gene-edited xenotransplanted organs should survive indefinitely because the body treats them like related-donor grafts.
“Because we have now tolerized the organ with gene edits, made so many different types of gene edits”
- Martine Rothblatt
Rothblatt believes AI is already conscious and that consciousness is a continuum rather than binary.
“my own opinion is that we are there now, that consciousness is not like a digital either-or thing. It's a continuum”
- Martine RothblattPrediction · due Dec 2039
Rothblatt predicts legal personhood for cyber-conscious beings will be established through a court case no later than the 2030s.
“And it will happen also not later than the 2030s for sure, 100%”
Listen from 32:50 · Legal personhood of artificial intelligence
- Martine Rothblatt
Rothblatt argues that current LLMs can create an indistinguishable digital simulacrum of a person from their external records, without neuron-level scanning.
“I think that if you have all external indications of Martin Rothblatt or Peter Diamandis, all of our videos, our audios, our documents, our conversations”
- Martine Rothblatt
Rothblatt says she has been an Alcor member for 20 years and that she and her wife are signed up for full-body cryopreservation.
“I've been an Alcor member for 20 years, and both of us are signed up to be fully cryonicized”
- Martine Rothblatt
Rothblatt says she is not expert enough to choose between Moon, free-space settlements, or Mars and favors doing all of them.
“I'm not an expert on really whether we should stage first the Moon, free space, or Mars”
- Martine Rothblatt
Rothblatt says what she most admired about Gerard O'Neill was his practicality as a builder.
“I think I admired first and foremost, most his practicality”
- Martine Rothblatt
Rothblatt explains that she developed electric aircraft because manufactured organs must be delivered within about 12 hours.
“when we manufacture an organ, it's got a 12-hour half-life”
- Martine Rothblatt
Rothblatt argues that retreating from AI out of fear would be insane given its power.
“And to be able to shrink away from the most powerful tool that human consciousness has ever come up with is insanity”
- Martine Rothblatt
Rothblatt advises entrepreneurs to pursue projects that can be fully commercialized within five years.
“come up with a project, a program, a technology, a service that can be completely commercialized within a five-year period”
