Aging Can and Should be Stopped | Linus Petersson | @TEDxStockholm

Aging kills everyone. Both the good and the bad guys.

Indeed

Notice there isn’t one for aging yet

Society is obsessed with happiness But happiness requires being alive Aging kills us all A society-wide effort to cure aging is needed ASAP

Our longevity biotech deep dive for Social Capital crossed 350k views (way more than we anticipated). The full report is private. For investors looking at longevity biotech, here are two bets worth understanding: 1) The overcrowded bet: cellular reprogramming. Bezos, Altman, and Brian Armstrong went in early, and NewLimit just raised $435M from tier-1 VCs and Eli Lilly - a genuinely bullish signal. Still, only two studies show a lifespan gain in normal mice (7-12%), so don't expect systemic rejuvenation from the first generation of epigenetic reprogramming therapies, but they'll very likely show efficacy against specific diseases. It might not be too late to enter the field, but it's definitely not early: three companies with only preclinical data are already at unicorn valuations. 2) The asymmetric bet: growing and preserving organs. Today up to 75% of donated hearts and lungs are wasted because they last only hours outside the body, and globally just ~10% of the need is met. The companies fixing that, building new organ sources and learning to bank them long-term, are early, and many are still in stealth. We personally know who's building what, and it's still possible to get in at low valuations. That's where the alpha is hidden. For the @chamath's @socialcapital deep dive, we assembled a group of 17 leading scientists, founders, and experts. Much of the useful signal is offline: who’s building in stealth, which founders can actually deliver, and which science is real versus merely well-promoted. With that work finished, we now have capacity for the next longevity biotech project for a family office, fund, private banking team, or private investor looking at the field. Beyond deep dives, we can help you source stealth deals, run due diligence, build custom intel tools, or launch client-facing longevity products. Know someone who runs a family office or fund and is into longevity? Share this with them. Want details? Let's jump on a quick call - DM.

I wrote a piece about Bryan Johnson’s diagnosis with autoimmune gastritis. Link below.

Best book on longevity right now imo

Happy 250th birthday, America! 🎂🇺🇸 To put that into perspective: here are some animals that live even longer—some of them alive today were probably around when the Declaration was signed… 🧵

@VinAmbleNaess Jag beskriver de evolutionära teorierna om åldrande - bl a Williams - i min bok :) Nej, vi kommer sannolikt behöva omfattande genförändringar. Men det är okey, så länge det funkar. Kryonik är paradoxalt nog enklaste att få att fungera (dock endast nedfrysning och bevarande).

@LinusPeters Det var inte mkt att stå till svars för, må jag säga. Vad säger du f ö om George Williams tankar om antagonistisk pleiotropi? Finns det en långsiktigt hållbar väg framåt utan genmanipulering?

Vilket är det största intellektuella missförståndet ni har gjort er skyldiga till under era liv? För min del troligen att jag som ung var kommunist.

I watched Anthropic’s full 100-minute AI for Science briefing. Here’s what you might’ve missed from the Claude Science launch. 🧵 (1/6)

@MRefoi @ExpressenDebatt @Expressen En möjlig lösning är att förlänga den friska livslängden Se denna nyligen startade läkarförening för longevity: svensklongevitymedicin.se

Välfärden står för en växande demografisk utmaning: fler äldre, fler kroniskt sjuka som lever längre, men färre i arbetsför ålder. Ändå handlar valrörelsen om nästan allt annat. Vem tar hand om oss när vi inte längre kan ta hand om oss själva?🐝Läs min senaste i Expressen.

Super great news

We are working on it 🤝 🐈

'Adjusting O'Neill cylinder image as per request' chatgpt telling me what it's working on - love it!

@VinAmbleNaess Visst är det fascinerande! Jag har gjort samma sak - supermärkligt att evolutionen inte förklaras bättre i grundskolan, man måste läsa om det själv för att verkligen greppa det

Jag har under de senaste månaderna börjat sätta mig in i evolutionsteorin, bl a genom att läsa Dawkins böcker. Kan säga att det har varit några av de mest spännande månaderna i mitt liv. Det är så mycket som man tror sig förstå, fast än man i själva verket vet nästan ingenting.
