I'm no AI expert, I don't have a lot of domain knowledge but what irks me about reading through this entire blog post is the idea that we are hinging on a definition of AGI that apparently accounts for 95% (!) of "economically valuable work" while basically not talking _at all_ about the trades. No mention of construction, manual labour, mechanics, welders, painters, nothing! Is the author trying to say that all that…
I agree that it doesn't account for blue collar workers, but it wouldn't surprise me if the balance, purely in terms of financials, was actually that unbalanced. I'm not saying it's correct or fair that a trader sat at his desk can contribute £20 million to a country's "output", while a builder, working his backside off could maybe add £100k, but that's the world we live in...
But anyway about it, if there is suddenly an influx of manual/physical labor poured into the market, labor prices will drop far below the living cost and all hell will eventually break loose.
