Can confirm that travel out of LGA is brutal this evening. Numerous planes stuck on the tarmac despite many cancellations and delayed departures. Now 3 hours late and counting with no end in sight. Pilot is getting virtually no guidance from air traffic control. I guess this I the new normal.
The departure delay at LaGuardia #Airport (#LGA) has increased to 121-135 minutes and is still increasing. #AirportStatusBot

I enjoyed two recent empirical papers on AI+Law, but realized they have somewhat different implications—in particular, about whether AI tools are actually useful for lawyers, or are too likely to err. I wrote up a blog post thinking through how to reconcile them: www.wilftownsend.net/p/is-ai-actu...
