Lithium batteries were a French invention. MIcrchips were German, English, and American (before DARPA).
Apple stole from the French Minitel which had a integrated PC and public internet before the US. NASA was Nazi scientists, and the Manhattan Project depended on the breakthroughs in nuclear science of the Italian, Fermi, who was the most significant scientist. The Americans who made ARPANET would have done so in the private sector if their work wasn't claimed by DARPA for national security reasons.
None of this means national debt is a good thing. If there were no DARPA, it all would still be worldwide. As a matter of fact, it was already happening at RAND and the British NPL.
Government debt, DARPA not necessary for any of it.
