I find it highly unlikely that vat meat would totally replace livestock. For starters, a large portion of the world doesn't have refrigeration or reliable transport infrastructure, let alone industrial labs. Even in developed areas, you have to take into account the large existing demand for pasture raised meat. Vat meat simply has externalities associated with it – civil infrastructure, educational overhead, perception issues, etc – that make it so that it can't compete with traditional livestock models in many areas. Realistically, vat meat competes with factory farming, and not a whole lot else. Which, don't get me wrong, is fantastic all on it's own.
