That was an excellent talk, containing some really great analysis. The analysis was so clear and thorough though that I was puzzled why it left one very important matter very fuzzy and poorly defined --- the title and main topic of the talk, of all things!
This is the problem: the word "jobs" (or equivalently "work") means two very different things to us, and these two things have been conflated into one single idea by our history over hundreds of years. Those two things are: (1) Doing something useful in a place of employment, and (2) Getting paid for it and using that money as the enabler of our personal survival.
I put it to you that your talk conflated the two ideas as strongly as everyone else does, and used the fear of losing (2) as the basis for examining whether AI would eliminate opportunities for (1). This is a crucial distinction to make, because survival is a non-optional imperative for most humans, whereas having an interesting occupation is merely nice-to-have and can easily bear periodic interruption.
I am an engineer, and as an engineer let me tell you something that isn't a secret among engineers but is rarely stated so directly: the practical purpose of engineering and of the science which underpins it is to eliminate (2) from the burden carried by humanity, and to enable a focus on (1) --- in other words, to give you the time to do something interesting with your life. It is sometimes said that this is the aim of civilization too, although a better observation would be that having to work for your survival is not civilized at all. Indeed, it is barbaric.
I expect that you will be giving that talk again, as the subject is a very interesting one and is highly topical today. I would definitely recommend though that in future you explain its title in more detail, because very few rational people would complain if AI eliminated the need for humans to work for their survival.
