I'm not at all conviced. They point out minute, small progressions in the direction of automation and then extrapolate that to 'the professions we're so used to having will wither and die because AI, that's why'.
What, so because I can read WebMD I'm suddenly in the same ballpark as a doctor with at least a decade of education behind him? Some people can figure some medical issues out sometimes. Maybe your GP has slightly less people with stupid questions. Doesn't mean the whole profession is devolving.
How many actually finish that and use it for something in their work life? Shockingly little. This is also implying that teaching as we know it is doomed because some MOOCs do reasonably well. Besides, since when is teaching is only about giving presentations?
sigh. Pack it up religious leaders, it's time to go home, there's an app for that now.
Perhaps the book is better than this, for example discussing discussing the inherent complexities in those professions and the difficulty of automating them. The hand-waving that happens here is awful, though.
