Besides such uses in improving traditional agriculture, I believe that the future of protein production, which is needed to supplement plant-based food, does not stay in making fake meat from animal cell cultures, like many attempt to do today, in order to sell to rich vegans.

In my opinion, with animal cell cultures it is extremely unlikely to ever be able to produce proteins at a competitive cost. By competitive cost I mean that any such proteins should cost much less than chicken meat (per protein content).

What I believe to be the right solution, because this should be able to produce high-quality proteins at lower costs than from any animal source, is to use cultures of genetically-modified fungi, which produce some high-quality proteins, e.g. whey protein or egg white protein. There already exist genetically-modified strains of the fungus Trichoderma, which produce such animal proteins, instead of the enzymes that they normally secreted into their environment. Such proteins can be separated from the fungal culture medium by ultrafiltration, in the same way how one makes from whey or milk whey protein concentrate or milk protein concentrate.

It doesn't need to be cheaper than the cheapest meat to be competitive. If there's some social or moral incentive to avoid real meat, that adds value to plant based alternatives.

Fungi protein sounds cool though. I would totally add that to my diet. But I also think insects are an underutilized protein source, so I might be an outlier

		Even when your personal budget would allow spending more for food, a price that is higher than that of meat is a serious red flag, indicating that it is likely that such a substitute for meat has greater environmental consequences than producing meat. There are 3 reasons for avoiding meat. One is the ethical reason, because during the last century meat production has transitioned everywhere to using methods that can hardly be considered anything else but continuous torture. There are also certain health risks associated with meat and there is also the reason that the real cost of meat may be greater than it appears to be, due to negative environmental consequences (i.e. pollution). If some kind of protein extract or some kind of fake meat is more expensive than real meat (per protein content), you can be rather certain that the negative environmental consequences are worse than for real meat, because the higher cost is likely to be determined by the consumption of more energy and of various kinds of chemicals during the production of the meat substitute.

vegan options lack flavor/texture. cost isn't the main issue

		Not everyone craves the flavor/texture of meat, but everyone needs an adequate intake of high quality protein. Including protein powder as a cooking ingredient does not do much for improving the taste of food (though the food definitely feels more satiating), but it ensures that it is healthy enough. Even if I liked meat, I never felt any kind of addiction to it. There are many years since the last time when I ate meat and I feel no need to eat again, as long as I have a lot of other options for food that is tasty and healthy. For several years I have not used any animal protein sources, but this forced too inconvenient constraints on what I could eat, so eventually I gave up and now I use in cooking some whey or milk protein concentrate powder, whenever it is necessary to increase the protein content. This has provided much more freedom in menu choice. So for me, if instead of having to buy protein extracted from whey or milk (which costs about the same as chicken meat, i.e. many times cheaper than protein concentrates extracted from plants, which must use much more complicated processes than the filtration of whey or milk) there would be the option of buying similar protein from a fungal culture, that would be enough to cover all my needs. From other comments that I have seen about the fake meat products, I am pretty sure that there are many others like me, who do not care whether they eat meat or not, as long as they eat some good food.
