Reading the discussion here, I can't help but thinking that people are defending their own philosophies: OOP vs FP vs DOP vs etc. I wish the author had killer applications or killer examples in different categories, like can I code an operating system easier, can I code a database easier, can I create a complex streaming job easier, can I write a library as complex as Apache BEAM easier, can I write a compiler easier, can I create a web framework easier, can I write a JSON parser easier, you get the idea. Or maybe examples that contrast existing solutions: how do I use DOP to write a better RxJava? how do I use DOP to write a better SqlLite? How do I use DOP to write a better graph library? How do I use DOP to write a better tensor library? how to do use DOP to write a better Time/Date library? You know, something that's so compelling and so obvious.

This confused me as when I hear data-orientated I think data structures that are optimised around minimising CPU cache misses by using better alignments, using enums where possible, not storing results of simple calculations etc. There is a popular book and popular talks on the subject. Probably confuses other people as well I'd imagine
