Vigilance and compassion
I swear to god, I’m gonna go full Indiana Jones on these fucking billionaires.
Hear me out: replicate the parts of a holodeck.
The reality is it wouldn't matter if it's synthetically produced meat, it's still going to have the same proteins and chemicals as it would if it came from an animal, which is what people (myself included) can smell on people who have consumed them. Eating garlic makes you smell like garlic, eating dairy makes you smell like dairy, eating meat makes you smell like meat.
I think the implication that we're smelling the concept of sin is very funny though.
My pet theory on this is that it's because most vulcans are vegan or vegetarian, and many humans still eat meat and other animal products. The diet thing is confirmed canon, but I can confirm being able to smell… meat smell(?) on people who eat it.
