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.
