Go is Google's language, not ours

I do mean that, and I do mind it a lot when I'm so used to just being able to erase the generic.

There are performance implications to type erasure, to be sure, but when our computers are mostly all future machines from beyond the moon, I'm more interested in minimizing the impedance between my brain and a solved problem.

This is the only non-bad consequence of type erasure I'm aware of. On the other hand, a lot of code I've written in C# would be impossible or severely hacky without type retention, like "new T()", "T is Thing", finding all classes that are derived from T, etc.

TBH, I'm just as happy passing a factory method in for that sort of thing. Because it allows you to do both and pick the one that makes the most sense for you in a given situation.
