Because Carbon is labeled Google, you became interested. Fine. But on the opposite side, because I understand that It's all about context, I'm not. Carbon has its use-case, inside of Google. Outside, it doesn't mean squat.
Engineering is the art of choosing the right tool in one's toolbox according to the context.

Nothing new under the sun, but still disappointing to see the sad state of our industry.
