Plenty of languages can get a solid standard library to write most code with, but only elixir gives you a modern, simple standard library with the tools to scale an app as high as apps can be scaled.
Whatsapp famously got to 1 billion messages a day with only 11 engineers on the BEAM (the VM that elixir runs on). It has proven itself immensely capable at the highest levels of scale so the only thing for anyone to decide is whether the stdlib and tooling is to their liking (speaking mostly in the context of networked IO bound applications, which is most things on the internet)
I probably worded my statement poorly, but my intention wasn't to claim it was the only language with a great stdlib. I would disagree that go has a good stdlib, I think it's quite poor, but I do believe plenty of other languages have great stdlibs.
