Everything is luck. You ability to learn, acquire and utilize knowledge, physical ability, not getting struck by lightning, being able to play basketball at the level of Lebron James, etc. None if it was earned - some dice were rolled when you were born and that's it.
> You could be the best [whatever] in the world, but if you're on your couch and disconnected, nobody will ever notice.
That is entirely based on luck. Were you born with the correct genetics and environment to get you off your couch or not?
> You can be among the best and be at every conference and active on every forum, and do well in every competition, and be first to launch with every idea, and get funded every time, and still lose badly, repeatedly
There's no difference between getting struck by lightning or being born with the right genetics that give you determination, intelligence, work ethic, etc. All luck.
I don't get this fixation with acknowledging how lucky one is when all of it is luck. We should be concerned with optimizing society so that we get to a point where no human has to struggle any more.
