I am another developer who has never really suffered as a result of a lack of generics. Personally I really like how dead easy golang code is to read and understand. God forbid golang become a language where untold amounts of logic can be packed into a single line of code, resulting in near mathematical levels of complexity which always require more time to understand. Like most complex concepts in life, I suspect the number of developers who can effectively use these tools is rather small compared to the number of people who think they "need" them. But hey, I'm a vim programmer who doesn't like to have to rely on a bloated IDE to be able to deal with the code that I am interacting with so I might be a minority.
