As technologies develop and become cheaper, they might be able to substitute for workers of all skill levels, and since the supply of smart robots and 3D printers can potentially become unlimited, this would lead to an equalization of labour endowments across the globe. At the same time, robots do not generate additional demand. As a result, trade flows driven by differences in labour endowments could potentially run dry with considerable consequences for current trade patterns. On the path to this extreme outcome, it is likely that trade patterns will evolve with the skills and adoption of additive manufacturing and robots in production across sectors.
