I didn't say that, I said that there are different visions of a better future.
I also didn't say that I have a problem here, only that I would prefer things going another way.
You are attacking a comment I didn't write and had no intention to write.
You agreed with GP who stated they would prefer Elon Musk had started a cancer research firm instead of SpaceX, and you said 'I would prefer solving Earth's problems too'.
(Personally I'd prefer cancer research wasn't conducted by 'a firm' at all, but that's aside.)
What was the 'better' in reference to a 'better future' mean?
Aha, so you weren't comparing different futures, you were comparing now to a type of future that you weren't committing to (and certainly weren't suggesting a future with Musk running a cancer-curing-firm would be better than a future with Musk not curing cancer for profit).
Perhaps you can understand why I was confused.
It's hubris to declare that your vision inherently provides a better future.
Happily you are completely free to start your own project(s) to 'solve Earth's problems' too -- it won't get in the way of what others (in this case, Musk) is doing, and you can look forward to basking in the glory of curing cancer, etc.
Unless the problem is that other people aren't working exclusively on the things that are important to you?
