Prediction by 2030: construction workers and tradespeople, like electricians and plumbers, will NOT work on new buildings.

Humans will only be needed for repairs and renovations to older buildings. As all new buildings will be built and maintained by robots.

Because if a house can be 3D-printed and finished by robots, the buildings will also be designed to be repaired by robots too.

For instance, have a plumbing leak in a new building? A robot could be dispatched instantly to fix the pipe, at no additional charge and without any delays.
