Future generations will look back on this era's treatment of animals as barbaric. They will have the benefit of being able to grow vat meat identical to any steak and perform drug testing purely in-silico, so they will not need to use animals in the way we do now, but still, when you remove the economic/scientific rationale and look at the fundamentals of our treatment of animals, you can't help feeling at least a little bit saddened by it.

Both of these issues have at their core the same question: are we gatekeeping "sentience" or I suppose, moral consideration, really - behind the rather utilitarian "so what's it done for us lately?"
