No idea about cheese, somebody is probably working on it. I would make a guess that the market for artificial milk is not worth the investment for most businesses, vegans, vegetarians and plant-based people moved on to plant milks and I think they're here to stay. There is a Swedish producer making high fat oat milk which apparently works really for coffee foam. My perspective is the question of whether or not plant milk vs cow milk is nutritionally equal doesn't matter since cow milk is not really required in modern society. It's an incredibly calorie and fat rich product that's intended for a developing calf, it was useful for humans living in harsh, winter conditions prior to industrialized farming but we can make up those calories elsewhere now.

Nutritionally, cheese is interesting due to the calcium content and vitamin K needed to absorb it rather than calorie content. And requires large amounts of cow (& sheep & goat) milk to create it. If artificial milk was possible, it could be made by traditional processes into the traditional cheeses we use for our varied cuisines. Direct artificial cheese I imagine would only get to market in one or two varieties (likely American cheese slices for artificial cheese burgers, or Parmesan for seasoning pasta).

It's a good point but I don't personally believe there are many modern humans outside of some small communitues that actually need to eat cheese for it's nutritional value. That said I understand it's often one of the harder things for people to give up when transitioning to plant-based diets.

Why does "need" have anything to do with one's diet? Cheese can be sustainably produced, and as an aside it tastes fabulous (I encourage you to try it).

I have zero intention to transition to a plant-only diet (we almost all already have "plant-based" diets, that term is offensively transparent marketing hand-waving for "vegetarian"). However, I certainly don't look down upon anyone for their individual dietary choices.

I don't really care for that term either but I used it because "vegan" has become such a loaded term in these kind of online debates, probably due to it often coming from the animal welfare angle and all sorts of silly hypothetical questions being offered from both sides. As for the cheese, I'll pass, you can keep it.
