on a first view, I think the cost-effectiveness of egg replacement precision fermentation R&D is the same order of magnitude as my (low) estimate of cultivated chicken meat R&D. Your precision fermentation estimate: roughly 1 layer hen life spared per dollar. My cultivated meat estimate: roughly 10 broiler chicken lives spared per dollar. But lifespan of layer hen is ten times longer than broiler chicken, and suffering intensity is about the same, so in terms of avoiding suffering, both are comparable in cost-effectiveness
