Go over Python may not be a magic bullet, but it's a damn useful tool nevertheless. While Go does not magically scale to datacenter-level systems, python cannot, without significant work, use even the resources on a laptop. There's a huge range of problems that are larger than 1 core and smaller than 48 cores (or 72 cores, or however many are in your largest server). And as the sibling comments have mentioned, straight-line single-thread performance is not irrelevant. Starting with a language that's slower than perl isn't a good beginning.
