Would a hard wired prejudice include being fundamentally biased against old people?
Within the context of the pie-in-the-sky subject we're discussing, calling for citations seems kind of pointless. We're all just speculating and talking about what-ifs.
I suppose my main concern is that if learned prejudices (against race, religion, ideology, age, economic status, etc.) cannot be eliminated by regenerating brain matter, then a potentially fatal error could arise for society since some prejudices can be virtually insurmountable for many humans. Such an error is often solved naturally when the leaders of the previous age die out.
Just like when a computer system has become corrupted or broken, turning it off and on again can be the most simple and effective solution, so can death and rebirth be an effective solution for when our collective mental processes become corrupted.
Well, since US elected national office is pretty much 30 and over, that's the only way wars can be declared.
But there's a reason why there's the movie cliche of the old cautious king being toppled by the young warmonger. On average, young people are a lot more prone to violence. Put them in charge of a nation, and I have no doubt that wars would increase rather than decrease.
Yes, of course the elderly possess great wisdom, but they are also highly inflexible when it comes to thinking of new solutions to new problems.
But a lot of that is because your gray matter doesn't work as well as you become elderly. If that weren't the case, we could have young energetic minds that also are wise dominate in society.
