I think one thing I have seen over the years is people making extreme assumptions based on experiences they hear via the grapevine, and seeing more perspectives seems like one way to counter that.
For example I have seen the claim here that CI systems were somehow new in the same timeframe that XP and Scrum were first written about and being adopted, and that testing was always an afterthought back then, etc.
If anything I think we were often building more reliable and higher quality systems in that timeframe, if only because there was more alignment that testing and fixing bugs mattered. Today I get responses like “quality isn’t just about bugs” if I am critical about the quality of a particular product. As if what users want is 2N as many features, none of which quite work rather than N features that are all solid.
