With all due respect here - "20 years of successful online dating" sounds like an oxymoron! Unless you're choosing to date and to not enter into a long term relationship?
With all due respect, this seems like a Rorschach test? He didn't say "20 years continuously dating online"? People can date online a bit, get into a relationship for a quite a while, relationship ends, go back to online dating, etc.
This is semantics, but I think the parent's point is: if the relationship ended, was it "successful"? You obviously have different answers (and that's fine!)
Actually this brings up an interesting point: the article implicitly assumes that the winning condition, the optimal outcome, is a long term relationship. But is it? Certainly many rich guys don’t act like that (stay w one person for 50+ years). This is important, because if we don’t have a consensus on what the best outcome is, that would explain why we’re not getting one. There may not be a single optimal outcome for that userbase.
We don't need consensus since consensus is impossible with a large population. You just need a vast majority and the vast majority agree on the winning condition.
That's a big "if" imho. Especially, since there are more than enough instances of unhappy marriages in previous generations. Often people stayed in abusive relationships because divorce was heavily frowned upon.
