None of those are really inventions like Tesla made, I frankly think the privatization of space is a bad thing, Teslas are actually not environmentally friendly, and I think all of the space stuff could have been accomplished without him if NASA was given sufficient funding.
NASA could do it with enough funding, but that would require the government to increase their budget, which would take years, and in the end, NASA would become political because it is taking funds away from the military, which space explorations do not need. On the other hand Teslas are inventions in my opinion because of the fact that till the model S no electric car had very good designs, was fast or could reach even half of the oil cars total miles on one full tank, but now with the new roadster coming out it will be able to drive as much as the oil car and more than gas cars. Also, you are right that a Tesla car is not 100% good for the environment, but it is much better than any other cars pollutant amount.
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!
