OK, just cool your jets mister, everyone here is having a pretty civil conversation without you attacking people for 'pushing corrosive ideology'.

And in order to formulate that attack you pieced together quotes from two completely differently messages and people to make your 'point'.

I said they keep people from re-inventing solutions, however it was the comment you actually replied to which else claimed they were too complex.

I agree they are patterns which languages do not yet abstract over, but until languages do I think they are very useful patterns for programmers to be able to correctly recognize as they occur frequently enough that knowing the pattern saves a lot of time and work. When languages can successfully abstract over those patterns, then knowing them will be niche knowledge assuming new patterns cease to be detected by humans prior to their ability to be abstracted by a language.
