Right, don't have to think about compile time. Instead they sometimes have to think about post-compile time[1], i.e. code generation. Now you don't have to think about those weird bracketed capital letters. Just take care to check where you have comments[2] that happens to include directives to some external tool.
With how Go programming seems to work for some people, I can perfectly well imagine a system with commands that do code generation as a hook for other commands, or by 'listening to the file system' for changes in certain files. That could get out of hand pretty easily. And yeah, one can say "anything can be taken too far". Just like you said about generics. The difference might between having well-encapsulated and behaving mechanisms that does most of what you normally would need. As opposed to a "simple" system that just pushes the problem to another level, in more ad-hoc ways.
[1] I honestly don't know if the code generation typically is pre-, post-compile or a mix of those two. It's too complex for me.
[2] I thought single-line comments was supposed to be a safe haven...
Not everyone uses codegen or other tools. You can write generic-ish code in Go which is just runtime checked via vtable pointers (interface objects).
And of course, the loss of static checking means that one has to write more tests for mundane things. But again, designing tests requires "runtime thinking", designing statically checked APIs requires "compiletime thinking".
