That was true for horses until the combustion engine came along and it certainly won't be true for humans forever. If we automate all useful work that can be done by someone at 100 IQ or lower than half of the population will be unemployed.

In 5 years or less we might see a massive reduction in demand for human taxi drivers. What are taxi drivers going to do? These are typically not people who are well educated and capable of making a rapid shift into another field. And what do we tell them when they choose another field to work in, only to see that field be automated away too? At some point, won't we run out of carrots to dangle in front of the displaced?

Long term, yes. But it's also happened many times in history that sudden economic disruption has had a very serious cost. That things might be better in a couple of decades is of no help to people who can't eat or keep a roof over their heads today because of these changes.
