So we have to program the language just to work around the the language ???

I''m glad you're sharing this but this was maybe a bit too simple? There was a few interesting details in there but a lot of it was beginners stuff.

12:40 And they say GO has no magic huh?! This talk shows clearly that Go's maps are just one giant monkey-patched hack! I want generics in my code. I want pointer ariphmetics in my code. Why wouldn't they let me use generics? I don't wanna write tons of boilerplate code for every single type I use. Go's core devs are using "unsafe" features everywhere but they don't allow other programmers to do that because they think we are too stupid. Oh, they are so nice and caring.

Basically it just implemented map for certain types of keys (ints, strings). I am surprised that a "modern language" can not implement a generic hash map and can spend 26 minutes on it.
