The worse is not, that. I think the worse is that, unlike Java, a race condition in Go has a totally undefined behavior that can corrupt the memory of the entire system your Go app is running on. You can effectively shut down your computer with a race condition in a Go program, and it actually happened to me many times on Windows, with 3rd party Go tools that didn't handle concurrency carefully. Go concurrency is truly unsafe, C style.
