China afaik is currently doing exactly that, as well as a few companies in the United States. Its not something just as easy as "experimenting yourself" (although, that is a very simplified way to look at it.) This is decades of research, with billions of dollars. Countries like China can socialize some of these aspects, and seems to be doing very well. It still takes time and money, and research. All the while, the current leading companies are still also furthering their own research.
