"The previous one, the industrial revolution, created lots of jobs because the new technology required huge numbers of humans to run it."
This is factually wrong, but its easier to demonstrate with a thought experiment. Imagine you are a weaver or a smith. You have dedicated your life to mastering the craft and slowly produce products by hand. Now a textile factory or a foundry opens up. You will suddenly find it impossible to make your products profitably. Not only will you be out of work, but so will all of your colleagues in the rest of the country.
Or imagine you are a farmer, and then the green revolution happens. In 1870, 80% of the US population was in agriculture. Today, its under 2%.
In both of these cases, it will seem like the end of the world to the displaced workers. But new technology frees their labor for new purposes and uplifts the standard of living for everyone in society.
