I wonder if this will eventually lead to even more efficiency (less people involved in per output). Vertical farms lend themselves much more to standardization than conventional ones imo (many small machines instead of few big ones). If all the often-failing parts could be built in a way that they can be replaced automatically I can imagine a giant farm being run by a single guy who's main task is receiving replacement parts and sometimes untangling messes the bots don't know how to manage.

The other big benefit of being independent from environmental factors might also come in handy in space or as a cheaper alternative to fighting climate change.
