I'm just afraid that it will be impossible to distinguish between real meat and lab meat. You'll start seeing "lab meat" for sale that is advertised as ethical and ecological, but might actually contain mostly actual animals. Also, I fear that the fake meats we have today get totally replaced my lab meat, the same way fake meats like beyond and impossible mostly replaced the shelf space of the more tradicional veggie burgers.

In general I think it will be a net positive for veganism, but capitalism always has a way to screw us over.
