"will likely fail" is a surprising claim when it's not clear to me that vertical farming won't still have a chance to succeed

For vertical farming, the question at the limit shouldn't be comparing solar and a farmer directly using sun, it should be: can we vertical farm on land that was unsuitable for farming? Is the cost of land increasing while the cost of solar decreases?

[XorNot]

The cost of land in the city for living on is increasing much faster then the cost of rural agrarian land.

Which we absolutely should not destroy to try and build skyscraper vertical farms on.
