I will grant you that Carbon is still in its infancy, but when Rust was in the same youthful stage we never heard an end to all the people playing with it. You, even if not tried it yourself, definitely knew about it.
You've made up a fun idea, but reality doesn't support it. Google has not shown its weight carries anything. They have really struggled to get any for-profit business units off the ground since they gained the weight, never mind their hobbies! If anything, Google is detrimental to a project.
Lets also not forget Rob Pike famous quote regarding simple minds, as target audience.
