Those are actually wonderful examples to my point, because it was the state leading the manhattan project. It is the role of the state to engage with issues such as how to handle the new discovery in terms of national security, constitutional rights, etc.
I would even argue that, for such a disrupting discovery, some sort of international approach should be considered - everything from monoply risks through energy usage to economical risks if massive unemployment is possible. We instead have private interests dealing with (or ignoring) these issues by themselves.
It's something that already misfired with the advent of social networks, where many of the current issues could have been avoided if the state had actually showed up to engage with the problem.
