NYT on congestion pricing finds fewer cars, less traffic, more public transit, less noise, more business, and fewer car related injuries.

The study, published Dec. 18 in the Journal of Marketing Research, links survey data on GLP-1 receptor agonist use – a class of drugs originally developed for diabetes and now widely prescribed for weight loss – with detailed transaction records from tens of thousands of U.S. households. ...Within six months of starting a GLP-1 medication, households reduce grocery spending by an average of 5.3%. Among higher-income households, the drop is even steeper, at more than 8%. Spending at fast-food restaurants, coffee shops and other limited-service eateries falls by about 8%.

I am a somewhat odd duck in all this, being a “humanities person” who also learned to code and hack around on a computer at a young age. Therefore I feel it is especially incumbent upon me to demonstrate how coding agents can be useful to non-coders of all backgrounds, ages, and interests. Today, I’d like to do just that. I hope it is useful to as broad a range of people as possible, and in service of that goal, I am going to write assuming no prior experience with coding agents, command-line interfaces, or coding.

The trouble with these calculations is that they mire us in epistemically tricky terrain. I’m bothered by how quickly the discussions of AI become utopian or apocalyptic. ... It also forces thinking to be obsessively short term. People start losing interest in problems of the next five or ten years, because superintelligence will have already changed everything. The big political and technological questions we need to discuss are only those that matter to the speed of AI development. Furthermore, we must sprint towards a post-superintelligence world even though we have no real idea what it will bring.
