Earlier quoted context omitted.
> We can still accomplish big innovations without those innovations coming from, or being controlled, by nation-state private companies. We've ran high-risk R&D projects successfully before as public projects - Manhattan project, the space race & moon landing, ARPANET, etc. So you prefer nation-state nations over nation-state private companies. :-)
Though two of your examples (not really Manhattan Project) had very significant private sector participants.
The main difference is, ideally, the project was voted on by the public, and is being steered as such. A public-private collaboration, with the public driving it rather than it being entirely the domain of a single private entity for their own profit.
