I'm sure people said exactly this about burger patties before amazing plant-based burger patties existed. There's no physical reason this is not possible. And don't forget that making a steak is also much harder with cultured meat, that's why they're also starting with burger patties and chicken nuggets.

From a higher-level view, most meat that's consumed is not in the form of steaks. It's in the form of ground meat. If enough people switch to plant-based meats for let's say 80% of their meat needs, animal-based meat won't be able to compete anymore with the price of plant-based meats. So, for Impossible to reach their goal of getting rid of the animal based food system, they don't even need to be able to make steaks. Sure, there will always be meat, but it will be an expensive luxury and rarity that we will frown upon as society (e.g. like wearing fur coats today or hunting dolphins and whales).

> So someone whose subsistence depends on plant-based meat substitutes says their competitor are not good enough?

Fair point. But also consider why they started a plant-based meat company in the first place and not a cultured meat one? He had the experience, expertise and funds to do either.
