Building a brick wall sounds like a tedious chore; but it is difficult enough that it is a craft. Working corners, around windows, and adding ornamentation take training and skill. A robot now can do that faster than a human. The record for a human, 700 bricks/hour. The record for a robot, 1,000 bricks/hour. The robot doesn’t have to sleep and doesn’t get tired; so, the brick walls of a house could take weeks for a human to build, but only days for a robot. There may not be much job displacement, though; because there is a shortage of bricklayers. Maybe the cost of brick housing will come down instead.
