Plans to put a 25-story apartment complex on San Francisco’s Marina district sparked concerts about a future where the city’s waterfront is ringed by tall housing structures.

AI dialogues shifted political support by 2 to 3 points in trials, eclipsing standard ads. Roughly one-third of this effect persisted for a month. However, models optimized for persuasion proved more factually error-prone.

AI chatbots can persuade voters to change their minds
Conversations with AI can sway people’s political views. Concerningly, a chatbot’s facts are not always accurate, especially when it supports right-wing positions.

NYC>Chicago is legitimately a great corridor for high-speed rail, if states of NY, PA, OH, IN & IL could unite for it.

You could hit:
—NYC—20m
—Philly—6m
—Harrisburg—600k
—Pittsburgh—2.4m
—Youngstown—400k
—Cleveland—2.2m
—Toledo—600k
—Ft Wayne—500k
—South Bend—300k
—Chicago—9m

On a ~straight route
This is the Beijing-Shanghai corridor, which takes 4 hours and 18 minutes to cover 800 miles. That’s the same distance as NYC to Chicago, which currently takes 20 hours by train.

Everyone should be pointing out what is happening at CFPB. There is zero argument to be made here that this is being done to provide taxpayer value. The agency's budget is minuscule, averaging like $600 million/year, yet it has obtained $20 billion in payments from corporations to Americans

Trump fired the CFPB’s Biden-era leader earlier this week, putting in place Treasury Secretary Scott Bessent, who froze the agency’s work.

Plainly unlawful and unconstitutional. No one can issue such an order; the President and his officers cannot simply ignore an entity created and funded by Congress.
