...even just the giant warehouses like Amazon. The latter is about truck traffic mostly. I actually interviewed with Amazon a few years ago for a managerial position in their facility design and construction division. My background was in hospitals and I could not figure out why they reached out to me. Turns out that whole interest Amazon showed in drones was not primarily about home delivery, it was about building giant fulfillment centers that rather than humas pulling stock from shelves and packing it to send to all of us, it would be drones ad robots. They thought my understanding of complex building systems integration would help them go from basic warehouses to buildings far more complex. And their thought was to rather than build huge and sprawling single story warehouses, they would build taller strictures as the drones wouldn't care and it would lower amount of land needed. They were way too poorly structured in their departmental organization for me to consider it but it was an interesting discussion. I suspect they gave up on the idea as it's been years and they seemed real intent on moving that direction but I haven't seen anything that indicates they even built a prototype. Given staffing their fulfillment centers is supposedly one of their biggest HR headaches I really thought they'd at least try it somewhere.
