My prediction is the "theorhetical one" and quantum computing breakthroughs are currently heavily gated U.S. Pentagon projects and will be weaponized for global domination for the U.S. Deep State Monarchy.
If you had no regard for the U.S. Constitution, how would you use the "theorhetical one" paired with State voter rolls, the federal postal system, and "one big beautiful dataset" of private American data to influence the next public election?
Any action you take will be approved due to sycophants you apppointed, bribed, or campaigned for, and then contested in court long after you leave office / the country / existence. So don't let that be a deterrent.
