I wasn't saying that I think no one should do things that benefit humanity. Rather I was saying that you should only do what is meaningful to you as an individual.

Musk clearly finds what he does meaningful to himself and is not doing something he does not enjoy simply for the greater good of humanity.

Notch did not enjoy being part of something so large. I find it odd to belittle him for choosing the path of doing small things, since that is where something as impactful as Minecraft was created in the first place.
