Still, we can do something about it right now. We may need meat, but we don't need meat in every meal; if we reduced the consumption of meat, we could conceivably switch to more expensive, less efficient, more humane ways to grow animals.

If you can afford it, you can also only buy meat from non-intensive farming. Or stop eating meat all together.

I just don't think it's morally right to wait for a solution that may not ever come, or not for a long time. I eat veggie fake-meat often, and sometimes it's great, but it's not close to real meat and I don't know that it'll ever be accepted by most of the population.
