He's pointing out that labor has always opposed labor saving technology, despite that being the basis of our modern quality of life.
Many people who pointed out the Industrial Revolution becomes the basis of modern quality of life skip what happened in between the 17xx-18xx until today.
Things like Unions, Wars, etc.
What comes after new technology has always been the elite class owning them all and forcing everybody else to suffer until something managed the distribution of resources slightly better (War forces that).
In the past, "labor saving technology" has always spawned alternate jobs that people could take with some retraining. This time it might be truly different. If one day AI can actually do all knowledge work, there might not be anything left for former knowledge workers to do. There's no physical law that says new technology necessarily produces 1:1 new, different jobs.
