This seems like a fairly negative assessment of the facts. I think many people turn to online dating voluntarily, not as some sort of last ditch effort to find a partner. Au contraire, the people I found in the typical settings where you meet new people like bars, night clubs, and doing my hobbies, tended to be a very particular kind of person. I would never have found my current partner in any of those places, and I know the same to be true for many of my friends.
Online dating is just increasing your dating surface area by 10-100x fold.
