    NYT reporters are under a Cassandra-like curse where they get amazing scoops but have to hide it behind vaguely dramatic headlines

    This is not the main point but it is amazing that the NYT hed for "Facebook let Netflix and Spotify spy on your DMs" is "As Facebook Raised a Privacy Wall, It Carved an Opening for Tech Giants"

    “There’s already 20 million people who can build software - isn’t that enough?” No. Until making your own software is as accessible as writing your own book, we’re not there yet. Not everyone can (or wants to) write a great book, but most have the baseline skills to try.

    In the orientation for my PhD program, a professor recommended a biology class, but added “It’s probably too hard for someone whose background is, say, statistics.” I was the only stats major in the program, which he knew. He did not like me
