Yes, Type safe. You can not interpret something as a different kind of type via the use of interface{}. Contrast that with void-pointers, which make that so easy as to be a common bug-source.

It's not statically type-checked, yes. That's fine too, in my opinion, but also irrelevant for a comparison with void-pointers (because they also don't provide that).

In summary, interface{} is strictly better than void-pointers. Which was exactly my point. Equating the two is intellectually dishonest.
