Just because Taligent failed does not mean everything from Taligent is bad. Just because Google and Facebook were successful does not mean everything they did is worth emulating... such as open floorplans, continuous deployment, everyone-does-everything and other such crap.
My grandmother's advice to me on tractors, etc. was to never buy retail: get them at the auctions for the fellows who thought they could both pay dealer retail and be profitable.
In this case it's possible to recognise both that Taligent inadvertently subsidised production of a nicely packaged collection of "best practices" (taken individually, the TOC topics lgtm) and that shipping crap dominates designing (maybe even building?) according to best practices but never invoicing.
(I don't know if it's still true, but for a long time last century the "secret sauce" of Silicon Valley was that it was easy to find people who had just come off of one of these grand "new new thing" Потёмкин projects, and both (a) wanted to ship this time around, and (b) knew the best corners to cut to do so)
