This is more my personal opinion, but I think the military's budget should be reduced quite a lot, and funding NASA has always been political. The introduction of profit motive into space exploration cannot be a good thing. Also, Elon Musk didn't really invent anything to do with the Teslas, and it's actually more environmentally friendly to keep your old car than it is to get a new Tesla.
I mean what furthers technology and the world other than businesses competing. Also, it is better to keep your old car, but when it eventually does breakdown it is of course better to buy an electric car. The last thing is that Elon did not invent it directly, but he certainly helped it be invented.
But also many people thought going to space would be useless and that a space exploration company could exist was thought to be impossible and wrong for businesses to enter such an industry. That is why I admire Musk he took a chance with SpaceX and Tesla even though everyone laughed at him for thinking Space X could get as good as NASA and that an electric car company could compete with giant car companies.
Technically Elon is in a lot of debt because he keeps buying shares of his company so much so that he has to borrow money from capital banks. And he doesn't even see any of his shares. In the end, you won't change your mind and neither will I so let's just agree to disagree cause I don't have any new rebuttals left. so good debate!
