There is no chase here. It is the other way round.
Jensen wasn't an innocent victim, he was still an active, voluntary participant.
It's not that easy to rebuff approaches from women you're very attracted to; it's much easier to avoid having the opportunity come up in the first place. I think at the very least the moral judgment should be accompanied by some empathy.
I am going to guess Jensen isn't even looking for beauty, although that is certainly part of the deal. But someone who is also business savvy, understands technology, smart and somehow well connected to AI as well as a business partner in some sense.
And perhaps it is worth pointing out the obvious, this isn't a simple beauty trap, it is a pys-op.
Although there is part of that thinks. Could Jensen knew of this all along. And it was just a way to get business going.
But that's not really a defense of the behavior, and it's perhaps a sign that we should stop valorizing billionaires.
Nothing unethical about it.
What if Huang wasn't married/with family? Does he just never get to form close relationships after becoming successful?
But if you're married, with kids, and you're willing to throw that away to chase someone else, I'd argue you have a serious personality flaw going on there.
