It's a plough, it's a discer, it's a seeder? Are you kidding me?
Have you seen a large farm-scale tractor plough a 40 acre field? Have you seen the speed at which broadacre seeders work?
Can you imaging this contraption replacing huge harvestors or even being a serious consideration?
'Cause all farm fields are flat and perfectly suited for some massive mechanical gantry to span it's entire width.
Wow, some people really get carried away pushing "new technology" into places it just isn't suited to go.

In a greenhouse, planting and tending to seedlings maybe, large scale farming to feed the world's starving, not likely.

Not everything in the world can be 3D printed. Not that this thing is in any way a printer.
