Elon Musk's greatest contribution to humankind will be to end war. In a few short years from now, the Reagan era brilliant pebbles will be economically feasible. Which means nobody will be able to keep the nuclear gun pointed at America's head anymore. At which point the US will make Russia and China (and maybe Pakistan and India) an offer they can't refuse: give up all your nukes, please. We'll denuclearize ourselves too, but a bit later. If you don't like trillion dollar annual defense spendings, here's the cheapest way to get rid of that: make sure you're the only guy with nukes. In which case, you will stop seeing things like Russia wanting to invade Ukraine.
