The article is overly concerned with financial cost. Lab-grown meat doesn't need to, itself, directly displace meat through financial competition. Meat can be pushed out of the market by other factors:
--The increased world-wide food requirements making land-use more efficient for crops than resource intensive animal protein.
--Either pricing in, or social pressure towards, reducing carbon emissions can push production lower & prices higher.
Maybe other factors too, but these can, themselves, gradually shift meat out of the marketplace.
In this scenario, vat-grown meat won't be displacing traditional meat, it will simply be filling the gap left by meat as it leaved the market for other reasons.
