It might be worth considering just how much other physics could be done with these resources. Improve education and experimentation for many other investigations instead. There is still much to learn about fluid dynamics, the chemistry of water, alternative plastics, and many other open questions. The vast amounts of resources poured into exotic reactors could educate many more physicists, launch many more satellites, and operate many more laboratories. Moving forward with very large projects may effectively starve out other investigations that might ultimately have far more practical applications. In some ways this proposal seems more like a lack of imagination than a positive surplus of imagination.
