BlackRock controls over $10 trillion in assets - more than the GDP of China. Larry Fink - the man behind it - just explained on stage exactly how he got there: the acquisitions, the macro bets, why the U.S. deficit "will overwhelm this country." 35-min and you'll see how the world's most powerful asset manager thinks about capital, risk, and the next decade. bookmark & watch - the most important Fink interview of 2025.

We will likely have more lawyers in the future than today, because: 1) AI will cause so many more people to ask legal questions which will encourage them to need to verify or execute through an actual lawyer. 2) AI will cause an explosion of more and more exotic legal terms that lawyers will be spending even more time reviewing redlines or new cases around. 3) All the new areas of law that now are emerging around the use of AI itself in every single industry. AI introduces an explosion of IP, privacy, and regulatory compliance challenges across all verticals. This has historical precedent as well. Between the creation of the PC and the internet (both technologies that made the legal profession far more efficient), the ABA pegs active attorneys having gone from roughly 400,000 in 1975 to roughly 1,375,000 in 2025. When we make professions more efficient and automated, often demand for them goes up not down.

This has been my major issue transitioning from aerospace to biomedical engineering. In aerospace, EVERYTHING is up for debate. you wana put the wings backwards on a plane? fuck it, Sukhoi su-47. Oh you want intermeshing rotors? Kaman K-max it is. In medicine, people flex their credentials (“doctor here 👋”) and rely on prior art: “usually are not” “standard practice” “typically not” EVERYTHING should be grounded in first principles and rigorous testing. Medicine is not like that, because of people like Dr. Kelly Morrison who look at a miraculous full body scanning technology that can see through you at unprecedented resolution- LITERALLY SCI-FI TECHNOLOGY- and can’t imagine using it for preventative means- simply because people haven’t done that before. You could give a magic X-ray gun to some third world, medieval shaman or witch-doctor and the first thing they would say is “yo we should scan everyone and make sure nothing looks weird inside”. How is this not the obvious response? I can’t see a future in which everyone isn’t getting MRI’d and having their images analyzed by AI. The future of medicine IS PREVENTATIVE. i don’t give a fuck what any doctor or pharma company says about it. Their incentive structures have been broken for the last hundred years. An ounce of prevention > a pound of cure. Please, for the love of God, think a LITTLE outside the box for once!

OPENAI ROADMAP UPDATE FOR GPT-4.5 and GPT-5: We want to do a better job of sharing our intended roadmap, and a much better job simplifying our product offerings. We want AI to “just work” for you; we realize how complicated our model and product offerings have gotten. We hate the model picker as much as you do and want to return to magic unified intelligence. We will next ship GPT-4.5, the model we called Orion internally, as our last non-chain-of-thought model. After that, a top goal for us is to unify o-series models and GPT-series models by creating systems that can use all our tools, know when to think for a long time or not, and generally be useful for a very wide range of tasks. In both ChatGPT and our API, we will release GPT-5 as a system that integrates a lot of our technology, including o3. We will no longer ship o3 as a standalone model. The free tier of ChatGPT will get unlimited chat access to GPT-5 at the standard intelligence setting (!!), subject to abuse thresholds. Plus subscribers will be able to run GPT-5 at a higher level of intelligence, and Pro subscribers will be able to run GPT-5 at an even higher level of intelligence. These models will incorporate voice, canvas, search, deep research, and more.
