good partners are not modular components that can be easily replaced, you'll discover this when you find one.

You'd be surprised. Of course no 2 people are exactly the same, so you'll miss someone terribly. After a while, you realize that the so called scarcity of 'great people to date' is Hollywood inspired pseudo-romantic bullshit. (I speak as a man seeking women)

One of the biggest advantages of living in a time of so many people is that the number of great people, in absolute terms, is also greater

Not yet. OP's technology may change this.

Nor is their one soul mate in the world out there.

Most people want the same things, it is not hard or unique to find someone compatable, no matter how much we tell our partner how special they are, and they say to us.

ah yes, the ol' condescending "you'll find someone someday" line.

did you ever consider that some (many, actually) people are not optimizing for long term mating strategy, and are rather playing the game to maximize short-term sexual rewards?

or does that simply not exist as a valid goal in your worldview, because you refuse to acknowledge its legitimacy?

Please don't put words in my mouth. I just object to the other poster's utterly naive or sociopathic attitude. Unless you're 15 the idea of maintaining a relationship with someone you (smugly) consider replaceable seems pretty repellent to me to be honest, I wonder if she knows?

I feel you are overreacting if you consider the other poster's attitude "sociopathic".

it's a defense mechanism.

anyone who harbors views dissimilar to mine = crazy

especially in manners of sex, love, etc.
