This is not a problem of interestingness. This is a problem of skewed gender ratios. In India and China there are way more men than women. That means that some men will remain without partners regardless of what they do or how interesting they become.
That's their problem you might say. Sure, but only if you ignore the negative consequences of young men being unable to find partners.
The analogy to India and China is pretty good, aside from a few tiny differences, like the fact that most single males in the valley we're talking about intentionally came there from somewhere else, are hugely wealthy relative to poor Chinese and Indian workers, and that it's ever so slightly easier to cross a county line to somewhere less bizarre than Santa Clara than it is to emigrate out of India or China.
It's funny how I can post a ranty-but-true thing about how the world actually works (i.e. "having some table stakes attributes will not make you a 'pussy magnet'") and just get bombarded by people like you complaining about the dreaded ratio and philosopher1234 who clearly is wondering whether his girlfriend is about to leave him for a rock-climbing jazz musician who doesn't bathe or something.
All these dudes come flooding into an area to work in a dude-dominated industry and collect Big Valley Salaries and somehow this is a problem that needs to be worked out? If it's that big a problem, leave. Geez. How hard it that to figure out?
So now your solution is for them to leave and go elsewhere. That's fine, it's workable.
I just objected to this idea that they should work on their interestingness and that doing so would somehow solve the problem of them finding someone. I think you acknowledge that even if they all become incredibly interesting, they wouldn't all be able to find partners.
