Any recommendations on materials that teach these subjects?

I don't think it's your mistake. It seems HN automatically removes certain leading/trailing words from titles so as to reduce clickbait but it doesn't seem to be very smart about it.

If you assume all trees have no value in their context and/or no intrinsic value and/or the same value as any other...

Of course, because the tree has no value, right? As long as you call things you don't care about "externalities" you can trivially prove anything is a positive-sum game.

Nice. Now I'm curious, is there a list somewhere of other projects Google open sourced after abandoning?

It's been possible in other languages for ages, and some of them don't even require parentheses or a semicolon!

I might just be biased by selective attention, but it seems like more and more of these are popping up lately.

I feel like we will eventually recognize a variant of Greenspun's Tenth Rule as common wisdom:

> Any sufficiently complicated build system or configuration management system contains an ad hoc, informally-specified, bug-ridden, slow implementation of half of Nix.

(Although to be honest it might make more sense to replace "Nix" with "Guix"...)

I mean, Excel does have LET and LAMBDA now...

"Treat ideas like cattle... Except this idea."

Which part of this is not conscious effort? You just made a stronger case for such automated systems, especially for people who don't have good memory or abnormal levels of discipline and motivation.

And there's your problem. Regular users do not give a rat's ass about your shoulds. In addition, for example, I've never seen any serious UX bugs in Telegram, and I've seen many in Element. Regular users care waaay more about that than some vague notion of "reliability".
