Honoring this year's 38 by 38 award winners — trailblazers in their fields who are driving positive impact with every giant leap they take. The award is inspired by Neil Armstrong, who was 38 years old when he walked on the moon. Nominate an alum now: bit.ly/3KHIjF

We have lost a giant in the mechanobiology world. Mike Sheetz helped to define what we know of focal adhesion formation and their role as mechanotransducers. Sending his family, friends, and colleagues my warmest wishes.
My heart is broken as I announce the passing of my beloved husband, science partner and friend, Michael Sheetz. A remarkable scientist we packed 40 years of living into 20. Rejuvenation of senescent cells and mice in Press in Aging Cell; his last words were this was his best work

Things I'm sick of hearing from my employees: - Can I leave early today - I'll be late in the morning - My child is sick, can I rush off - I've got a doctor's appointment tomorrow, is that okay - I'm going to be late back from lunch, I've got some things to sort I don't care.

MEI -- love it. Like honesty, always the best policy. I try to bring my A game to work every day, and believe others should as well. Why? 1. I owe it to my employers to give the best of myself in exchange for the privilege of their support -- particularly in a field (basic research) where the return on investment is so uncertain. 2. I owe it to my co-workers, who rightfully expect me to pull my weight as I expect them to pull theirs. There's tremendous satisfaction in being part of a team where everyone strives to be the best. Plus, creative and productive output increases with nonlinearly with the effort of the team. 3. I owe it to those who work for me, to set a proper example, to make the outcomes as rewarding for them as possible, and to make sure their best efforts are not diluted by my not giving 100%. 4. I owe it to my family, my parents, and all those who have come before me to build this modern world of unprecedented prosperity and opportunity in which I live. 5. I owe it all those in society who sell me the fruits of their labor: construction workers, farmers, doctors, custodians, restaurant workers, etc. etc. etc. and who deserve to be paid in hard earned dollars. 6. I owe it to my children and all the generations to come, to pay it forward for all I have received. There is still so much need and opportunity to make the world a better place. 7. But most of all, I owe it to myself. I am happiest and most content when I feel I've put in a solid day's work and made the best use of my abilities: ""The only legitimate happiness is honest hard work and the surmounting of obstacles" -- Tolstoy
Today we’ve formalized an important hiring policy at Scale. We hire for MEI: merit, excellence, and intelligence. This is the email I’ve shared with our @scale_AI team. ——————————————————— MERITOCRACY AT SCALE In the wake of our fundraise, I’ve been getting a lot of questions about talent. All of our external success—powering breakthroughs in L4 autonomy, partnering with OpenAI on RLHF going back to GPT-2, supporting the DoD and every major AI lab, and the recent $1bn financing transaction—all of it is downstream from us hiring the best people for the job. Talent is our #1 input metric. Because of this, I spend a lot of my time on recruiting. I either personally interview every hire or sign off on every candidate packet. It’s the thing I spend the plurality of my time on, easily. But everyone can and should contribute to this effort. There are almost a thousand of us now, and it takes a lot to hire quickly while maintaining, and continuing to raise, our bar for quality. That’s why this is the time to codify a hiring principle that I consider crucial to our success: Scale is a meritocracy, and we must always remain one. Hiring on merit will be a permanent policy at Scale. It’s a big deal whenever we invite someone to join our mission, and those decisions have never been swayed by orthodoxy or virtue signaling or whatever the current thing is. I think of our guiding principle as MEI: merit, excellence, and intelligence. That means we hire only the best person for the job, we seek out and demand excellence, and we unapologetically prefer people who are very smart. We treat everyone as an individual. We do not unfairly stereotype, tokenize, or otherwise treat anyone as a member of a demographic group rather than as an individual. We believe that people should be judged by the content of their character — and, as colleagues, be additionally judged by their talent, skills, and work ethic. There is a mistaken belief that meritocracy somehow conflicts with diversity. I strongly disagree. No group has a monopoly on excellence. A hiring process based on merit will naturally yield a variety of backgrounds, perspectives, and ideas. Achieving this requires casting a wide net for talent and then objectively selecting the best, without bias in any direction. We will not pick winners and losers based on someone being the “right” or “wrong” race, gender, and so on. It should be needless to say, and yet it needs saying: doing so would be racist and sexist, not to mention illegal. Upholding meritocracy is good for business and is the right thing to do. This approach not only results in the strongest possible team, but also ensures we’re treating our colleagues with fairness and respect. As a result, everyone who joins Scale can be confident that they were chosen for their outstanding talent, not any other reasons. MEI has gotten us to where we are today. And it’s the same thing that’ll get us where we’re going, as we embark on our next chapter focusing on data abundance, frontier data, and reliable measurement to accelerate the development and adoption of AI models. Alex

Nick Saban said, "If you want to make everybody happy, sell ice cream, don't be a leader." Saban was a great leader. And he may be the GOAT of college football coaching. What makes Saban the GOAT? 👇
