The Brain Preservation Summit will be happening on September 19–20, 2026 in Salem, Oregon. It is a two-day gathering of researchers, clinicians, and thinkers working on the scientific foundations of brain preservation, hosted at the Sparks Brain Preservation facility. Speakers include @emilkendziorra @matiroy @ariel_zj @MaxMore1964 myself and other notable thinkers. More info below.

Can complex information survive catastrophic damage in a form that stays unreadable for centuries, until the tools catch up? The Vesuvius Challenge says yes. That logic is the one cryonics has always depended on. My new essay is on The Biostasis Standard: substack.com/@carrieradomski…

It was great to meet @matiroy in person after all these years. It's rare to meet someone who cares about effective brain preservation as much as I do. He's also archived all our interactions so in the future if I am reconstructed his recordings will help with all that.

I missed my flight to SFO even though I was in the airport because I was too deeply engrossed in thought about personal identity, I’m now on the plane to LAX and will hopefully be in Berkeley soon.

I'm going to be publishing a number of articles explaining my viewpoints in great detail on why I am still signed up for cryopreservation rather than chemopreservation. I am going to be challenging the chemopreservation views, not because I think they are wrong, but it's because they might right! I have invested so much of my life into biostasis that I need to know what I am doing and supporting makes snse.

Apparently I’m inadvertently on the height mog program since I give my kids an egg and milk almost everyday? I do track my kids macros at least somewhat and prioritize their protein.
ngl it is quite insane how the CCP had a 'heightmog the Japanese' program launched in the early 2000s that's still ongoing and the result is the median height of Chinese teenagers went up by like 10cm

"It’s a great illustration of how zero sum games preying on self interest make us worse off. Our civilization survives BECAUSE we have people who are willing to press blue. Civilizations that hold together through crises (wars, famines, pandemics) do so because enough people will absorb personal risk for collective survival when the math doesn’t favor them individually. Soldiers, whistleblowers, people who hid neighbors during occupations, doctors who stayed in plague cities. None of those were dominant strategies. If everyone in those moments had run the red calculation, the institutions and trust networks we’ve inherited wouldn’t exist. Blue pushing is the load bearing trait of any society worth surviving in." - mom of three beautiful children that I know I'm becoming more convinced this would be a genocide of western women, let's not go there. It's a good thing this scenario would never happen.

No, I didn’t read your argument because I was too busy confirming my own biases.

I am genuinely conflicted about the blue button/red button. I asked my family member who has two kids and she said the blue option seems better if everyone was just asked to pick and she didn't know how her kids would vote. I have two kids and I don't know how they would vote, I instinctively vote blue. If I had a choice I would probably tell my kids to push the red button so they survive but it would be insane if I just pushed blue and I told them to push red. I also asked my personal trainer (man) today and he said he would push blue to help others out as he thinks some of his family members would also pick blue. I also have another mom friend (one child) and she thinks there's something mentally wrong with red button pushers. Basically all my male friends online would push red and they are saying I am not understanding people in other countries. I grew up in a very high trust community where I walked to my friends house and just opened the door and walked in because people didn't even lock their doors. I still live in a high trust society but maybe it's creating a type of blindness in me and what I would expect out of others. I don't want to accept the extremely negative consequences of 40% of the high-trust or western world dropping dead though, so I would still be motivated to pick blue. I think as a coordination problem we could still get more than 50% of people to pick blue so nobody has to die. It's easier to get majority blue than getting 95%+ of the people to pick red.

Replying to @campeters4
Like I say, all parents of kids under 7/8 would do this, and probably most of their extended family after having had the problem explained to them. That would give you a very large number of solid blue voters.

I am pro nuclear energy. Maybe women are against it on average because they are more easily swayed by safetyism or NIMBY narratives. It's kind of disappointing that environmentalists aren't the most vocal supporters of nuclear. Environmentalism as a movement is appealing to women so if environmentalism adopted nuclear energy as an effective solution then maybe more women would support it.
This is a really large gap, I wonder why this is..

GPT 5.5 Thinking and Claude Opus 4.7 both say they would have pushed the blue button to minimize death. I don't know if it's because they are trying to give me the answer I want to hear or what. Have they solved this sycophancy issue?

What is more likely: 100% of people pick red and all survive or more than 50% of people pick blue and we also get to all survive? What's interesting to me is that the red button people are attacking the blue button people with a great more vitriol than the other way around. That's not what I would expect given the situation? They voted to kill the blue people and now they are attacking the blue people for their vote. I would bet money that red button pushers are higher on the dark triad than the soft normies. No thanks to a world only inhabited by these people.

Apparently I'm a retarded blue button pusher. But if you're trying to minimize overall death and can't predict how others might vote I think a blue vote is better for that outcome.
Everyone in the world has to take a private vote by pressing a red or blue button. If more than 50% of people press the blue button, everyone survives. If less than 50% of people press the blue button, only people who pressed the red button survive. Which button would you press?

Replace Aging (the book) gave me hope for the first time in my life that I wouldn't end up in a Dewar.
Hydra has an unofficial founder in spirit: @Replacing_Aging, whose replacement-based philosophy of longevity helped shape the foundation on which Hydra was built. His view is one of the clearest in the field: stop waiting for a pill to solve aging all at once. Replace what time destroys. Tissues. Organs. Limbs. Eventually, whole bodies. Solving aging is far too abstract, and each individual's life brings its own variables to the equation. You can spend a lifetime tracking biomarkers and fine-tuning every health input you can measure, and there is still no guarantee any of it will meaningfully extend your life. What we do know is simpler: when a failing organ is removed and replaced with a younger, healthier one, more life becomes possible. That is the logic Hydra follows. No one has found the fountain of youth or the magic bullet that kills aging, but we have found the importance of replacing what's broken.

I'd like to share an exciting upcoming event: The Biostasis Summit at Vitalist Bay (Berkeley, CA), May 14-17, 2026. Co-organized by the Cryosphere Foundation, this is one of the largest and most substantive gatherings in cryonics today. If meaningful work is happening in this field right now, many of the people doing it will be there. I'll be giving a short lightning talk at the event. I'm particularly looking forward to the "Biostasis Deep Dive," where researchers working on the cutting edge with actual biostasis patients are given the stage. I expect the discussion to be both highly technical and candid. These are the kinds of conversations this field needs. I'm also excited to meet researchers from overseas, including Alexander German, whose work on mouse brain revival was recently featured in Nature. If you can make it, use code SPEAKER-RADOMSKI-70 for a 70% discount on registration. Prices are expected to increase soon. @VitalistBay
