What do you guys think of vertical farming?

Vertical farming, the best solution to support an ever growing population or just a scam?
IMHO it has a lot of potential but not being able to grow grains really is something that should be tackled sooner rather than later. But I could see this being used by self sustaining communities to provide lots of food while using very little space. And it's technically more environmentally friendly than just using vast stretches of land to produce the same amount of food.
Everything is limited in what crops it can grow, if we can maximize the productivity of space in semi urban areas then we can use the other space for crops that best suit it - grains are great for distant rural farms because they store so well, same with potato, etc where you can fill a huge truck and drive into the city once every season but stuff like greens and herbs lose so much after only a few days from being picked so you either need expensive chilling or other processing or a small lorry taking a load every few days which really isn't a great way of doing anything
