There's a Wikipedia article with some history: https://en.wikipedia.org/wiki/Astrology_and_astronomy

I imagine astronomers have been sighing resignedly at dinner parties for a couple of millenia:

In the Hellenistic world, the Greek words 'astrologia' and 'astronomia' were often used interchangeably, but they were conceptually not the same.

In his compilatory work Etymologiae [c. 625], Isidore of Seville noted explicitly the difference between the terms astronomy and astrology (Etymologiae, III, xxvii) and the same distinction appeared later in the texts of Arabian writers.

I find these neologisms helpful as they quite precisely capture the intended meaning and are easy to remember. Doctorow is an impressive and entertaining communicator, and being an author he needs to market himself and his work, so fair play to him for trying to score a hit follow up to "enshittification".

The earliest use of "centaur" in this sort of context I know of is Kasparov's advanced chess idea from the late 1990s: "a bad (chess) player with a good computer program will always beat a good player with a bad program". How far we travelled since then...

He talks about it, and you can see some of these works in a YT vid here:

Quote from Cameron Lilja, Nasdaq's global head of index solutions:

"It is not necessarily representative to have a company that's big and could have a sizable representation in the index to keep them out for that long," Lilja said in an interview. "We're seeing share and corporate structures change - and companies that are staying private considerably longer are thus growing to be truly mega-cap companies before they even come to the public markets."

There's been fewer IPOs recently so Nasdaq and competitors are all racing to woo the few big ones to list with them.

Seems equivalent to removing road safety rules for the least-tested, most-powerful new vehicles only.

The market can remain irrational longer than you can remain solvent.

A long-term principle that I think does still apply.

...On reading more it seems of use primarily in adversarial situations, so not-so-much resonant.
