Go is not thread safe. It even allows data races in its own runtime. Go 1.25 fixed a nil-checking error that has been sitting in the runtime for two years.

Generally, Go will let you compile just about anything when it comes to channels, mutexes (or not..), WaitGroups, atomics, and so on. It usually compiles as there are no static checks, and then just fails at runtime.

That’s a good point. I remember that in the earlier days of Go, there was a lot more optimism about the compiler’s future ability to statically decide more about the program than it currently does. It’s unfortunate that the language never got there.

Sadly, given Google’s new culture and all the people who have left, it seems unlikely it’ll ever get there.
