When Will We Run Out Of Names?

Hey, Vsauce. Michael here. According to the U.S. Census Bureau right now, in America, there are 106 people named Harry Potter. 1 007 named James Bond and eight people named Justin Bieber. They're just aren't enough names to go around. There are more than 300 million people in America but a hundred and fifty thousand last names and five thousand first names is all you need to name 9 out of every 10 of them. In order to stand out now, and have your own unique name, you have to be a bit more creative. O', 'Diarrhea Planet' or 'Betty's Not a Vitamin', which, by the way, is no longer true. Betty became a vitamin in 1994. What about Twitter handles or email addresses? Have we already reached peak username? We already find ourselves often having to use abbreviations, initials, numbers or just choosing something completely different. Will our children or our children's children live in a world where the only remaining Gmail addresses is are just random strings of alphanumeric characters? Are we approaching a name crisis? And if so, should we even call it a name crisis, lest we use up yet another precious name?
When are we gonna run out of names? Perhaps it's already happened to you. If it hasn't, when? Ten years, twenty years, a hundred, a thousand. When will someone with your exact name become famous? So famous in fact that your legacy changes forever to just being not the person people think of when they hear your name. And for that matter, when will every reasonably memorable pronounceable band name or brand name be taken? When will authors have no choice but to just start reusing book titles? According to Rovi Corp, owner of AllMusic.com , the most used band name is 'Bliss', followed in order by 'Mirage', 'One', Gemini', 'Legacy', 'Paradox' and 'Rain'. In the past when fewer bands had already been created and you couldn't just Google up every single band, overlap was easier to get away with and one word band names were plentiful. But now, after years and years and years of band formation, well, we have The Who', but we also have 'The What?', The Where', 'The When', 'The Why', 'The How' and even 'The The'. Maybe you already share your name with someone famous. But if you don't, how long will it be until you probably will?
I mean, new famous people are popping up all the time faster now than ever before because of the Internet and they are gobbling up top Google search billing. Maybe it won't happen until long after you've been dead but shouldn't the reservoir names, not taken by notable people, eventually run out? Computer scientist Samuel Arbesman approximated how many famous people there are alive today and I think his calculation will be helpful. You see, he points out that if we allow "famous" to simply mean "being notable enough to have your own Wikipedia page", well, because there are 700,000 living people with Wikipedia pages right now, that means one out of every 10,000 people on earth today are famous. Assuming at the least that that proportion remains constant since 255 people are born every minute, that means every hour a future famous person is born. Their name destined to become primarily associated with them, not everyone else who shares their name. All of those people will be relegated to disambiguation or the post-nominal, not the famous one.
