Imagine we lived in a culture that did not believe "government is always bad at everything". Government could then pay Google-level salaries and provide Google-level resources to the top minds in the world and give them free rein to tackle problems like this. It's worked in the past, such as Manhattan project or moon landing. But I don't think it's doable nowadays because of the anti-government political culture. Even when government is fully funding things these days the work has to be farmed out to private interests.
