Re point 1), I don't disagree. I'm not saying that those jobs should be perpetuated beyond the point of usefulness, but that if we're prepared to apply that argument to make-up artists, then there's no reason not to apply it to actors, poets, novelists, graphic artists, etc.

We've lived with point 2 most of my life. Natural language processing, for example, turned out to be far more contextual, ambiguous and complex than its early proponents initially thought/hoped. But things have changed dramatically even in the last few years, and will do so more in the future, rather quickly. I feel like we're more or less at the point they were in 1900 re. powered flight. Looking back at a century of failed attempts, one would be forgiven for scoffing at new ones - but one would be wrong.

However, I am not a professional prophet, despite being without honour in my own country.
