Out of curiosity I decided to try and run the numbers on how much Netflix you can watch for the energy cost of a ChatGPT prompt As far as I can tell it's between 5.1 and 10.2 seconds, depending on which end of the 2019 IEA Netflix energy usage estimate you use

Here's a wonderful interview with @janagallus
UCLA Magazine just ran a feature on my work (and a bit of my life) “What’s Your Incentive?” 👉 newsroom.ucla.edu/magazine/jana-… #incentivedesign #fieldexperiments @uclaanderson @UCLA
It would take Voyager ~75,000 years to reach the nearest star. No doubt a spaceship that leaves earth later will arrive sooner.
This is simultaneously a tremendous achievement (one light day is really far!) and a sobering realization that the universe is an incredibly vast place. In 50 years, Voyager has traveled ~1/1500th of the distance to the nearest star (Alpha Centauri, ~4.27 light years away).
Who's working on an LLM-based tool to identify the 100 most poorly written or obsolete laws and regulations in each jurisdiction? It identifies the problem, provides evidence of why it needs to be changed and suggests new wording that a legislator can review, propose and enact.
Sometimes the speed limits do seem unreasonably low, but the answer is to change the law, not break it. Ditto for many other such cases where the law is poorly written.

"The lack of a human driver is no longer the reason [Waymos] stand out most from regular traffic. They do so because they follow the speed limit. Indeed, cyclists and pedestrians are so used to drivers going 5, 10, or more miles per hour over posted speed limits, that Waymo’s…
6. Reduced demand for parking spaces and parking garages 7. Increased need for pick-up/drop-off zones near most commercial buildings. 8. Fewer families have second cars, or even first cars 9. Demand for "status-signalling" cars drops (or does it rise?) 10. Lower insurance rates
This will have a bunch of second-order effects, e.g. 1. A big decline in traffic accidents and fatalities, 2. More people willing to live and commute further from city centers, changing land values 3. Increased congestion leading to the need for congestion pricing, 4. The…

We're officially authorized to drive fully autonomously across more of the Golden State. Next stop: welcoming riders in San Diego in mid-2026! ☀️
The US is losing blue-collar jobs for the first time since the pandemic—year-on-year job losses have hit 59k as manufacturing industries lose jobs at a rapid pace while growth in construction & transportation has nearly zeroed out
New data shows the number of international college students enrolling in American schools for the first time decreased by 17% this fall. These students pay tuition that subsidizes American students, and many stay in the US afterward to work as scientists and engineers. Policies…
AI agents are increasingly acting on our behalf. What does it mean for the economy, and how do we make it "better?" Lab Faculty Lead Professor Sandy Pentland has a lot to say about it. Watch his talk at the ADIA Lab Symposium here: youtube.com/watch?v=Amxav9…

"[The book] reveals a kind of balancing act, where humanity has won opportunities from AI, but also has to guard against unintended side effects that may challenge us in ways we never expected." -Forbes Sandy Pentland's Shared Wisdom is available now: tinyurl.com/shwis
Sad to see people eagerly eat up this viral post that assumes correlation is causation. The causal effect of school funding on outcomes is heavily studied in economics. Giving poor schools more money improves learning & economic outcomes. Sorry to burst your bubble.
It doesn't matter how much money you put into schools. Here's a cross-sectional overview. Per pupil spending and math scores.
tl;dr It pays to check both Lyft and Uber before booking a ride. I hope someone makes a simple app to automate this (and overcomes the ride-hailing platform's efforts to break it).
updating our paper abstract: "in this paper, we demonstrate that there is insane alpha in checking both Uber and Lyft before booking"
