Just because someone frames an opinion in technical terms doesn't make it relevant to the discussion. There's a mismatch in the levels of abstraction, claiming that a lack generic programming is Go's downfall for mobile application development. Some people clearly feel quite strongly that generics are a vital part of any language. But they don't really tie into the difficulties of mobile app programming, which are (i) resource contraints, much tighter and differently prioritised to desktop and server programs; and (ii) dealing with GUI libraries, which typically have massive numbers of functions, nests of callbacks, and are generally fiddly to program. Generics can be a help with various algorithms but it's far from clear that they help with mobile-specific issues. Your parent poster is the typical person who shouts about generics in every Go thread. Like the people who spit bile every time Stephen Wolfram is mentioned in any context, it gets pretty tiresome.
