Comparing SpaceX with Uber is like comparing apples to oranges.SpaceX may be inventing stuff but Uber solves a common problem for everyone around the world. I don't need to think twice about going from point A to point B without much hassle. And coming to the invention part, I believe rocket science is as much difficult as serving million requests concurrently and consistently without affecting user experience anywhere in the process. If Uber's product is evading taxes and regulations, then Google's products are just trying to make you click on some random ads.
As a fellow hacker, you know what hard problems i am trying to talk about and we should respect that. I agree uber has some problems internally but they don't deserve to be disrespected.
