I think of lab-grown meat as harm reduction. It will almost certainly be more resource-intensive than a vegan diet, but less so than raising an entire animal for the fraction that becomes edible.

It will also produce less waste, or at least better-controlled waste, than raising an entire animal. But again, more than a purely plant-based diet.

I can't give you numbers, but really, I can't see any reason for you to switch away from a vegan diet if you're satisfied with it. However, a lot of other people will switch from an animal-based diet to one that is somewhat more responsible and causes considerably less pain and suffering.

All meat eaters live with a certain cognitive dissonance on that, which most simply ignore because they consider plant-based diets insufficient. And as a vegan you know that a healthy plant-based diet isn't always easy -- though made a little easier recently by some highly processed products that aren't really all that much better for health or the environment.
