There's no single 'best language', and it depends on what your use-cases are. But I'd say that for many typical backend tasks, Go is a choice you won't really regret, even if you have some gripes with the language.
* The Dremel is approachable: I don't have to worry about cutting off my hand with the jigsaw or set up a jig with the circular saw. I don't have to haul my workpiece out to the garage.
* The Dremel is simple: One slider for speed. Apply spinny bit to workpiece.
* The Dremel is fun: It fits comfortably in my hand. It's not super loud. I don't worry about hurting myself with it. It very satisfyingly shaves bits of stuff off things.
In so many respects, the Dremel is a great tool. But 90% of the time when I use it, it ends up taking my five times as long (but an enjoyable 5x!) and the end result is a wobbly scratchy mess. I curse myself for not spending the upfront willpower to use the right tool for the job.
I find myself doing this with all sorts of real and software tools: Over-optimizing for fun and ease-of-entry and forgetting the value of the end result and using the proper tool for the job.
I think of this as the "Dremel effect" and I try to be mindful of it when selecting tools.
