I feel like Go falls much into the latter category. I needed to write some code recently that did DSP. There is not any equivalent for this like SciPy in Go that bundles together lots of the common DSP operations you need. There are lots of partial implementations in different libraries of for e.g. filters, all of which use different interfaces. A lot of this I think is because of the lack of SIMD, you can't get brilliant performance out of the box with a Go implementation because the standard compiler doesn't support it.
