Very possible. When I read the headline, I was immediately reminded of one of Asimov's short stories, where he details a future in which 99% of the population can learn using brain-machine interfaces that directly download information into our minds, called "Tapes." The story was about the tiny, strange contingent of the population had to do this weird, interactive process called "learning." The "hard way" may have benefits, but such benefits may also either be negligible or simply not exist.
For emotional bonding, compatibility filtering is the easy traditionalist benefit, but it's often not very effective, so us maybe citing it as a real benefit is contestable.+iPan Baal
The traditionalist argument is silly, but I don't really see anyone using it here as a primary argument. I only see tangential references to it in speculation that "the hard way" probably has unquantified benefits.+David Jones
Yes, those are pathologies, but they're also instances where physical modification (damage, in those cases) of the brain causes behavioral modification without the subject being fundamentally aware that something changed. I don't think it's much of a stretch to suggest that chemical tweaking may be as "stealthy" in its behavioral modification. Granted, chemical castration is a rathe brutal counterargument, but not particularly applicable if we are to discuss the hypothetical limits of chemical tweaking.+Gregory Rader
Oh, absolutely. I actually didn't see "chemical bonding may wholly replace having actual relationships" as the article's thesis. It suggested that, at some point likely far down the line, chemicals could be used to greatly help.
