Rich people would try to develop a technique to identify and transfer their wealth to their next life. If no way exists to identify people apart from memory, you would probably get a lot of people claiming to be the same wealthy dead person.

Things also might get ugly if people or states try to punish the reincarnations of people for whom death or a life sentence wasn’t determined to be “enough” (though on the other hand, I suppose murder would be less heinous a crime since the victim just comes back and isn’t gone), or if people seek out the reincarnations of dead spouses, since those reincarnated people would now be babies.

On the brighter side, if those past memories are good enough, education becomes a lot more effective since it doesn’t just teach the current person but all their future incarnations until the subject matter gets forgotten or out of date.

Anxiety and, due to a manufacturing bug or something, a second anxiety instead of something else.

I renamed my cat because of this guy. I don’t really like to change animals names from what it was at the shelter in case they’re used to it, and I have a cat named Mel, who I suspect was named for him because there was another nearby cat in the shelter he came from named “Gibson”.

So I’ve renamed him after Mel Brooks.
