Thanks, @prateeks. Looking forward to the chat and meeting fellow builders tomorrow.
Hosting @shashanknd for a fireside chat this Thursday in Palo Alto. Shashank founded and scaled @Practo and is now building Cent, a preventive healthcare startup in India. I am very curious to dig into how medical imaging, genetic testing and biomarkers are changing longevity and what role AI plays in all of it. If you’re interested in longevity, healthcare or building in India, please join us. Thursday, October 15, 6pm Palo Alto Register here - luma.com/gr67jqy4

What is happening in math is remarkable. At the end, it all just seems to be computation. It requires so little math, but a huge amount of (semiconductor) engineering to support it.

AI improving SNR. Works well Now looking for a detector for AI Slop 🤔
What if, for any scientific claim, you can search 100M+ papers to find the strongest evidence for and against it ⚡️in 1 second? That’s now possible with Evidence API! 🚀 paperclip.gxl.ai/evidence-ap… For example, does drinking coffee reduce diabetes risk?

So cool. It would have been great to have a ticker next to each for the number of lives saved or QALYs added
Lilly has a cool wall of fame for all of its molecules that honors the scientists who invented them.

Health is the ultimate currency. GDP is driven by individuals' spending, and there is no greater need than health. Conciseness is the driver of health. Quantum and Space are two of the least explored frontiers for understanding and spreading conciseness, and we have barely scratched the surface. Lots to discover and invent here.
a truth hidden in plain sight: every big tech and frontier lab is going to become a bio company - google: demis' alphafold & isomorphic - meta & microsft: esm & bioemu protein models - nvidia: bionemo software stack for biochemical models, joint lab with eli lilly - openai & anthropic: both making the rounds about breaking into bio, strong bio reasoning models, wet lab - elon's empire: likely crossover between neuralink and xai (eg controlling ai with ur mind) - apple & amazon: not as frontier, but consumer health devices, onemedical acquisition, pharmacy mastering the most complex machine created by nature/god (the human body) is the ultimate test of superintelligence

Incredible. Innovation takes decades. Your first principles are the only support through decades of rejection.
In 1992 Peter Ratcliffe received this rejection from Nature. Almost 30 years later he won the Nobel Prize for the same discovery. Don't lose faith in the things you believe in.

Now this is super intelligence.
For decades, researchers have sought materials that sort electrons by spin while their magnetism cancels. In 3 days, 90+ Opus 5.5 agents helped us uncover two room-temperature magnetic semiconductor candidates in simulations: YBaMnFeO₅ and KV[Cr(CN)₆]. KV[Cr(CN)₆] was synthesized back in 1999. Its predicted ability to sort electrons by spin appears to have been hiding in plain sight for 27 years.

We launched Cent Check two days ago - the love and response have been incredible. Thank you. India has reached the moon, finding disease early should be well within our reach. We’re building @centai_health to make early detection accessible to many more people. Here’s a closer look at Cent Check. 🎬

Whoa. Didn't know that. FinTech Innovation.
Banks in India make about $20 billion a year -- half of their profits -- by paying customers ~2.5% (vs the repo rate of 5.25%) on the money in their savings accounts (~$800 billion).

Today we’re launching Cent Check, a full-body health checkup that stays with you for a year. It grew out of what we learned from the first 10,000 people who came to Cent. We started Cent to help people find serious conditions before symptoms appear. Most of the people we’ve scanned felt healthy when they walked in. Yet about 25% had a finding worth acting on, and for 1 in 40, the finding needed immediate medical attention. For most people and their families finding something serious early can make an enormous difference to the treatment ahead and its financial burden. But a scan is only the beginning. We kept asking how we could help people understand their results, act on them and see what changes over time. Cent Check is our answer. It combines advanced imaging and more than 100 biomarkers with a doctor-led health plan, a six-month checkpoint and doctor support through the year. The Cent app helps you keep track of it all. A health checkup should do more than tell you where you stand on one day. It should help you look after your health throughout the year. We’re in Bangalore, Mumbai and Delhi NCR today, and working to bring preventive care to many more people. Here’s a first look.

Talk about balance. Steve jobs quote about “not wanting to being the richest person in the graveyard” is such good principle in life.
Living simply is linked to greater happiness. A review of 259 groups of people found that the more someone cares about money and possessions, the lower their well-being, and the worst effects show up in how people see themselves and in risky behavior. Helga Dittmar and colleagues at the University of Sussex combined 753 results from studies around the world. Their review was published in the Journal of Personality and Social Psychology in 2014. People who see possessions as a sign of success and a path to happiness showed the strongest link to lower well-being, and people who simply care about money showed a weaker one. Risky health habits, compulsive shopping, and feeling bad about yourself had the biggest links. Life satisfaction and bad moods showed smaller links that still held. Jobs and schools that reward materialistic values made the link stronger, and it also shifted with a country's economic growth and the gap between rich and poor. Unmet basic needs were the best explanation for the pattern: feeling capable, feeling free to make your own choices, and feeling close to others. A life built around stuff may crowd those out. Most of the studies took one snapshot in time, so the direction isn't proven, and the effects were modest. Across 259 groups, the people doing best were the ones who felt capable, free, and close to other people. pubmed.ncbi.nlm.nih.gov/2534…

One thing I’ve learnt over 18 years of building Practo: conviction compounds. Leaders who have built through multiple chapters carry context no playbook can replicate. They know what must evolve, what must remain true and why. That depth is a powerful advantage for everything we build next.
