There was no change of mind. They always had generics in their minds. See the Go FAQ: https://golang.org/doc/faq#generics https://golang.org/doc/faq#generics "Generics may well be added at some point. We don't feel an urgency for them [...] we continue to think about it. [...] The topic remains open." These sentences have been in the FAQ since Go 1.0. Maybe people should start to believe them. They have gathered experience with the current language, their generics design drafts have improved over the years, and now they feel like they have something that might fit.
