It might be helpful to note that this article was written for the FT (as he mentions at the very bottom.) While it aphoristically may make a “pre out of you and me,” I presume neither the author, nor the subscribership of FT _are_ indeed (or wish to be) constrained to the language of a typical 10-year-old. Presumably the same would apply to the readership of HN.

We don’t know if the author _can_ explain it like we’re ten, but I think we can be reasonably certain they understandably chose not to.
