I made this post as a comment in Brad's interview about No Man's Sky with Sean Murray (the Four Questions one) and decided I wanted to leave this as a blog post so I could reference it later.

According to an article which explains that "it's difficult to meet people because traveling across the galaxy will take a really long time" (which is its own can of shitty worms) quote: "18,446,744,073,709,551,616 procedurally generated planets" will exist in the game.

I'm going to do some shitty math here. Let's say you somehow managed to visit, oh, 1,000,000 planets in this game on which you named things. Does that seem possible? That you'll visit 1,000,000 planet during your playthrough? I'm gonna say "maybe if I spend 500+ hours in the game." So, what are the chances that a person will hit one of your planets? Well, looking at the numbers, the chances are 1 in 18,446,744,073,709. Or 0.00000000000005%

Now just multiply that by, let's say, 10 million people playing the game and the chances that just one, only one of those 10 million people will see anything you touched is.... 1 in 1,844,674 or .0000005%

Do you see, now, how little that matters? You're naming things for yourself, not anyone else.

Edit: Did I say Galaxy? I meant Universe. The developers have indicated that you play in a Universe made up of many Galaxies. Keep that in mind if you mull these numbers over in your head and think "well, if you're on the outside of a round disc going towards the center, you'll eventually have to cross paths with someone." Guess what, it's not that simple, so the reality is closer to the numbers I've given.
