Completely agree with the sentiment of the author my question is why is this happening? I see a lot of comments here mentioning things like groupthink or specialization as the reasons, but how can really smart people suffer from groupthink or how can generalist engineers not afraid to write sass/graphql/js all in the same line of their pure React component want to specialize? I hope this thread doesn't turn into a shit show, but instead sheds some light on the real reasons.
