Don't you think it's a self-contradiction? There's 0 evidence to support valuing hypothetical descendants of these monkeys over hypothetical descendants of your children.
Secondarily, I value some sort of backup intelligence system as a protection against human intelligence monoculture. Though one could reasonably argue that adding a human brain-fold gene to a monkey does make it more human-like than truly independent.
I suppose I'm hoping that we get better at this and eventually are capable of uplift that yields not necessarily human-style intelligence.
I don't subscribe to an absolutist view of the veil of ignorance. My life is, to me, of higher utility than yours or the random children who I actively choose to let die daily.
So I'm going to act in a manner that preserves my life. That seems natural, after all. The other day I bought a new phone instead of saving a child's life. I don't even like this Pixel 5 that much. I like my life very much. Think about how many kids I'd kill for that.
