Earlier quoted context omitted.
The thing is BM (and others) aren't trying to create vega/vegetarian meat. They are trying to make meat in a sustainable way, so it has to taste more like beef/pork than chickpeas or tofu if they want to get the main market. They are still not there.
As a pretty hardcore meat-lover (we had sous-vide filets tonight at home), I think Impossible is close enough on the taste and feel side for a lot of dishes that use beef (including hamburgers). They're comically far off on the price side, but if they could get price-competitive with bulk 80% ground beef, they would capture a large amount of that market, I think.
Now, if I'd known to look out for it, I'm sure I could have picked and found out. But since I wasn't looking for a difference, I didn't notice one. And that's coming from someone who eats a ton of (real) burgers.
