Yeah, as previously mentioned, I fully agree that nullable pointers kind of suck and exhaustive pattern matching on enums is strictly better. I'm taking issue narrowly with abusing the "billion dollar mistake" quote to exaggerate the severity of the problem.

It's a big problem in Java at least. In Go you have value types by default and they try to make zero a meaningful value.

It's not a big problem when you look at the problems that plague even the most popular programming languages. At this point I can only refer you to my previous posts because I'm repeating myself. :)

Which problems do Java and C# have that golang doesn't? Incidentally, both of them have solutions to the billion dollar mistake, which golang doesn't.

Which is arguably even worse, because it goes on undetected and the code ends up producing incorrect results silently.
