I hope they stick around (Impossible should be ok). They're not the healthiest, but they're a rare semi-reliable vegetarian/vegan option for when you go out to restaurants. Otherwise you usually have to eat french fries or pasta. And they're also higher protein which is difficult to find going out unless you want to cook all your food at home.
It varies a lot depending on where you live, I'm in Berlin and a lot of restaurants have more vege/vegan options than meat ones these days. Hopefully it'll continue and that path everywhere.
Well prepared tofu/seitan/mushrooms are delicious, nutritive, much more environmentally friendly and you don't have to ask yourself if they were raised ethically or in hell like conditions
It's not perfect, and I have nothing against meat per se, but I acknowledge that we can't eat meant 1-2 times a day every day sustainably/ethically and affordably
I have a coworker who came from Germany and that seems to be the case. USA still has very limited options. I don't mind, but I've come to stop going to restaurants outright due to the lack of decent options and only really go with friends for the social aspect.
