If this robot allows people with little time to grow vegetables in their backyard, you can argue that they will move closer to soil rather than further...
The reason people don’t do it is that commercial farming is so efficient once you factor in costs growing your own is not cheaper than buying from supermarket.
A lot of people prefer spending half an hour a day learning italian, or rock climbing, or whatever...
Some stuff is easier to grow, some is harder, but for example I barely did anything on my strawberry patch this year other than picking them when they got ripe. I'd say I spent maybe 15 minutes a month on the strawberries.
Now if you're trying to grow a lot of stuff then the time investment might increase but most backyard gardens don't take up that much time once you've planted everything.
Robot might help in a greenhouse setting but outdoors it's just gonna get mudded up and get fine, abrasive clay dust in everything. Needs to be way more ruggedized.
I suspect this varies by location and demographics. Being an older guy living in rural areas, almost everyone I know grows at least some veggies and fruit. Not everyone makes it a major part of their lives, but I'd be hard-pressed to find almost anyone I know who doesn't have at least a couple tomato plants, or some berry bushes.
