You're certainly getting older :). You're assuming that since the author writes about something obvious, they must belong to the "younger generation" and encountered it for the first time.

Meanwhile, the author finished their PhD in 2004, and wrote 3 books about Python.

Maybe not "by", but "for" a younger generation.

Which 3 books are you talking about? I can only find 1 on Amazon (and it has a grand total of 12 reviews, so... you know, not exactly a best seller).

Frankly it's a bit suspicious how defensive you are of this author, and combined with the blatant downvoting of my toplevel comment, makes me think there is some astro-turfing going on in this thread.
