The transition to vertical farming, would IMHO, allow regular farmland to transition to forest — which would help offset carbon — and reduce the cost for regular farmers bc the crops would grown in a more-controlled environment. So, what’s the holdup?

The scale of farming is probably beyond what you can imagine, vast fields of wheat, corn, and soy just for starters. How do you make that vertical in the real world? You’d need to build the same surface area “up”, maintain those structures, have equipment to handle it, etc. Vertical farming makes sense for some non-commodity crops with relatively high per-kg sale price, where the alternatives involve a lot of expensive shipping.
Even then, it’s a nice idea that doesn’t lead to reduced costs, but increased costs.
