Do you consoder economies of scale a technology? I ask because it seems to me that economies of scale in manufacturing and agriculture have been a huge driver in producing more with less inputs (especially labor inputs).

Economy of scale is a specialization of logistics, so yeah.

Gears or transistors are not required for something to be a technology; a technology is just a bundle of techniques.

Robotic automation will replace the majority of human related services in the next 50 years, much like vehicles replaced the need of horse for travel.

Any society that fails to embrace this future risks isolation and most likely, economic failure relative to those that do.
