Half way through their demo, there was a power outage at the farm (as happens from time to time). As it turns out, their [insert product] relied on a connection to either AWS or Azure for some key functionality. Power goes out, turns out they had been using the farm internet for that connectivity (LTE service was miserable in the region), so their huge machine just stops and sits there idling in the field. Can’t even command it to return back to the crowd. Meanwhile our drone is still running back and forth on our field area and we didn’t even notice that anything went wrong.
