Yeah, normally as quick to comment on casual ageism as anyone. But, in this case, it's the New Yorker and I think they're just humanizing the story. (And, per another comment, with respect to "knowing their audience" I expect the New Yorker readership skews relatively old.)
Humanizing the story via insulting/encouraging ageism toward a former MIT Chancellor (Grimson), and/or another well-known MIT Prof (Guttag) who is an expert in diverse CS sub-fields and has collaborated with the likes of Barbara Liskov? Given how long they’ve both been teaching and doing research, and how much cross-pollination there is between Harvard and MIT, it’s very likely both of them were influences on Malan himself.
FWIW, my wife also found Prof. Grimson to be “too monotone” and asked me “how do you stay awake during those lectures?” but without bringing age into it.
Side rant: I am the child of baby boomers, and I think their generation had it much easier than we do. I also get infuriated with the callousness and lack of empathy exhibited by many people from the Boomer generation. But rude retorts like “OK Boomer”, aside from being disrespectful, only encourage further callousness and lack of empathy.
I hate to read such articles. I don’t understand why they are so popular in the Anglosphere. It always comes off as if I am reading a failed fiction writer, not a journalist.
I don't exactly know how to explain why I like this writing style, but I really do. I even subscribed to the New Yorker for several years but ended up canceling when I realized how far behind I was falling in reading it. The dang thing comes every week and is at a high enough average quality level that each issue is worth reading cover to cover.
Also, a decent chunk of the content in the magazine is actual fiction by actual accomplished fiction writers (not "failed" ones). You don't tend to see it linked from HN obviously, but that's very much the vibe they're going for. Think of it as part commentary on the times and part literary fiction magazine. That may not be your cup of tea but it is appealing to lots of people.
