This is the shit about "rational" thinking that pisses me off.
you start with a premise that sounds reasonable: "Wouldn't it be good if future generations were better off than their parents?"
Then you throw out all the hard parts of the question like:
- what does it mean to be better off?
- would there be equal access to the technology?
- what would the social consequences be if there isn't?
- could one group of people impose their designs for humanity on others?
- have people tried this before? did anything go wrong?
Then you ignore all of history, pretend it's just a surface level question of technical ability and the only objections people have must be because they're stupid.
And voi-French noises you have yet another position to be smuggly superior in.
Like fuck, we do this to other animals and we get fucking sheep that die if you don't sheer them and get infections around their bum, chickens with a fifth the lifespan of their ancestors, chickens that grow so fast their legs sometimes break, dogs so fucking inbred they are a mess of health problems.
Maybe you could take a lesson from this about how fucking awful we are at deciding what traits are desirable and how twisted the logic of capital is. Or nah? maybe people who think a few random rich shits deciding on the perfect human will go about as well as other high modernist ideas are just idiots. That must be it.
