Robots can't replace most workers. Robots can do repetitive tasks very well and very quickly but when it comes to problem solving they fail and will always fail at these problems that arrive in a world built for humans.

A human world is very inconsistent and not all humans want the same thing. That house building robot is going to have to be able to adapt to each little whim that us fussy humans have.

Simply do a Google search about the sewer drain cleaning thing - you'll find hundreds of companies in any large city. Do you need to be schooled on supply and demand?

The article is written quite well but I personally think it is still very optimistic.

Take for instance this: I shoot video. I was interested in buying a 6-axis robot arm that is easily programmable that could hold about 1.5kg and have a reach of about 1.5m fully extended. By all means quite a small robot. I wanted it so that I could program it to move my camera and do movements like you find in the Kendrick Lamar - Be Humble video. A robot like this base price would be about $12,000 with a teach pendant to program it and that is a very basic robot. The one that was used in the video was a lot bigger and a lot more expensive ($60k or more) and it still has a slight shake in the video camera movement which I would not have accepted.

For many tasks there is no human replacement. A human is easily teachable and no special knowledge other than the ability to communicate with each other is needed to be able to pass knowledge from one human to another. A human can also multi-task, a human can problem solve even without having access to a huge database of knowledge to draw from (humans are better at solving problems in a human world).

Don't sell yourself short just yet - you as a human being are still valuable. I'd let you clean my sewer drain any time.
