I have no qualms with people making money. I like to make money myself. As long as I treat others fairly and take care of others, why shouldn't I be compensated for that?

I think in the end it comes down to values. I believe in things like ensuring that my negative impact on this world is as little as possible. While I try to maximize the positive impact on the other hand.

There is prior scientific exploration of things like Musk is testing. With proper protocols in place to ensure minimal suffering (and yes probably some suffering can't be foregone). Why not support these? Why do his own thing without these long honed traditions in science to also take the animals' suffering into account?

I would neither want to dismantle capitalism nor scientific inquiry. But I can't say that egomanical ideas (imho) thinly veiled in science for humanity don't make me want to forget my good upbringing.

But I admit. I just might be wrong, his intentions might be great and only this experiment failed in a horrible way.
