As soon as we learn how to cultivate some good quality meat in-vitro, we will stop killing animals and start to pretend to be different from the barbaric previous generations.

That's what people do in every ethical aspect, we circumvent it and pretend it's easy to solve, and then criticize the people that can't circumvent it due to some environmental issue. When that people is on the past, there isn't even a problem with this.

"As soon as we learn how to cultivate some good quality meat in-vitro, we will stop killing animals and start to pretend to be different from the barbaric previous generations."

In the very long term maybe. But even if cheap, good quality artifixial meat becomes avaiable by tomorrow - killing animals for meat simply out of tradition - will go on a long time.

Sure, but that's the case with all traditions. Plenty of things that westerners see as barbaric (slavery, ritual genital mutilation, institutionalized torture) are still common in the developed world (and often openly endorsed by western governments).

Edit to add: The bigger picture is that for a set of practices, even if they still occur on a smaller scale than in the past, that's probably strictly an improvement.

As a circumcised male who is disappointed that Guantanamo bay is still holding prisoners I’d suggest that the west still does many of the things you mentioned.
