My 42nd language track just got checked off as green. I think 42 is a good number to stop at: it’s a generational thing.
It’s been a mostly positive experience, certainly educational. There about a dozen languages I definitely want to explore further, mostly ones I had used in previous years, but also some new ones (Crystal, Ballerina, V, Zig…). There were also a few I hated and never want to hear of again, but I won’t name them!
(P.S. Though I went to the same university as Douglas Adams, we didn’t overlap: he graduated and left in June 1974, I arrived in October that year)
