Thanks - I didn't see that. Might actually buy that book.

As I said this is something that makes me deeply uneasy. I'm pretty relaxed about most "serious" issues...e.g. Climate change - I feel "it'll be fine & we'll make it work somehow". Looking at this problem I can't help but feel it will not be OK. And thats coming from a guy in South Africa - a society that is barely hanging on under the strain of inequality. SA is on the very edge of what the social fabric can withstand in terms of inequality & AI will cause inequality that is much worse.
