@Ribby Moreover, in some deep sense, there are levels. Even if Dalio's shorter version is too much of a reduction compared to the whole book, it is order of magnitudes less of a reduction compared to what happens today around us: quotes, bits, excerpts, and most of, TL;DRs. In that sense, perhaps you'd agree that _if only_ the reduction we were dealing with were like Dalio's short-book version.
