Food's always changing, and we are already using much less animal organs in our cuisine than even a hundred years ago. So yeah, no doubts it'll change even more over the next hundred years.

Some organs can be grown same as meat though, if there's enough demand. Even with steak meat, you would want it with structure, not as puree, which makes it not so much different from some of the muscle-based organs as heart or stomach. The prices would change, I'm sure. Niche products would necessarily be more expensive than mass produced ones.

But I wouldn't expect farm animals disappearing any time soon. It's not just meat we'd need to substitute, it's also dairy, leather, fertiliser, blood products for medical use, bones for food additives, and so on and so forth. For some of these, we have the technology already, but it requires oil as the raw material (like leather substitutes) or produces toxic waste (like fertiliser), and it'd need a lot of scaling up. For others, we don't even have good alternatives yet.
