After all else has been tried and failed, Kelly McGuinness &c. decide to do some actual research, and find ... there's no evidence to support the notion that Waymos would be safer than the drivers they would replace in NYC, and some evidence to suggest they wouldn't. Read the

There is a slightly different picture when you look at killed or seriously injured, where Waymo is still safer than human drivers but harder to tell statistically from rideshare

Why hasn’t AI increased unemployment? Today I’m sharing an essay taking on that question.

🚨NEW: In the 9 months after last year’s reconciliation law enacted unprecedented SNAP cuts, the number of people receiving SNAP fell by more than 4.5 million. Based on available data, we estimate that at least 1.5 million fewer kids are receiving SNAP.
