Go is an incremental improvement over the C++ ecosystem without all the legacy baggage.

By controling the platform, Google can leverage the ecosystem to attract and cherry-pick early adopters to the language.

Once the language becomes populat enough that the Enterprise starts to adopt it, Google will already be onto their next 'ground breaking' technology.

Once people settle on a perception they tend to hold on to it for life. One day soon people won't want to use Java. It'll be seen as "our Dad's language". Steve Yegge (ie now a Googler) said as much during his OSCON 2007 talk.

The value isn't in the language/platform, it's the people who adopt/build/use it.

Microsoft knows this, developers are what kept them afloat during a decade of stagnation in product development. Oracle thought they could buy their way in by acquiring Sun; except, while they were busy suing Google, Amazon sprinted ahead of the pack with their cloud services platform.

This is how the biggest players make long-term investments. Guarantee an abundant stream of top tier talent and success will follow.

Strategically, the hiring pipeline for Google doesn't matter. It can train new hires in Go or whatever, it's historically hired around non-language competencies to some degree. What matters is being able to introduce breaking changes by leading the development effort and hosting critical repositories: e.g. 1.4 broke subrepository references by changing locations.

Strategically, incipient potential competitors have a dependency on Google and those little breaking changes means that Google can add friction to their development pipeline. Google will, even if it didn't say so on the package, Angular 1 vs. 2 is an example of how willing Google is to leave developers in the lurch and create ecosystem FUD...think of all those now dubious tutorials and "should I wait" forum questions.

I don't think its just happenstance that Erlang allowed Whatsapp to become an existential threat to Facebook with a handful of engineers. Language stability matters for startups more than the big boys.

YMMV.

Go is an incremental improvement over the C++ ecosystem without all the legacy baggage.

Go has little to do with C++, it throws away many useful features (generics, const-correctness, RAII). Also, where C++ encourages reuse of existing C libraries, Go 'penalizes' it by making C calls expensive and placing restrictions on interaction with C (e.g. you cannot store pointer to Go data structures). There are reasons for doing this, but all these things make Go pretty much unacceptable for people who are in C++'s niche.

If Go can be compared to any language with traction, it's the later Pascal family of languages (Oberon) and Java pre-generics. It even makes some of the same mistakes (first no generics, then probably retrofitted generics).
