Imagine guys like Musk, Bezos, Zuckerberg or Thiel cloning themselves. That's 100% dystopian. We would never be able to get rid of madmen! Power corrupts and makes the powerful just weird and unable to make rational decisions. That's why people in power need to be replaced regularly to have a stable society.
I agree with the second part, but I’m not convinced cloning those people would lead to other copies of them (not that I’m advocating for it, either). Your environment/upbringing/opportunities shape a lot of who you become. Musk famously has kids who find him abhorrent, I see no reason to believe that he’d be a competent father even to himself. Especially since the kid would have siblings who could open his eyes to the shit his father does, and if there’s one thing Musk is known for is gullibility to accept anything fitting his world view. I don’t think being a greedy unhappy (by his own admission) asshole is genetic.
Would they be the same person? I'd risk sounding ignorant and say they wouldn't. They could be fed the same food and knowledge, but what shapes them is every random factor encountered in the real world. How would they react when reading or hearing about all the hate they are guilty of without ever participating in it? It's not their lived experience.
