My takeaway is that there's a more pressing risk from humans automating too much too fast with something approximate and suboptimal, but "good enough". There're already plenty of situations where city planners enforce macroscopic policies that result in widespread discrimination and such, and that was with best intents. The promise of AI is that entire horizons of industry open up with opportunities for automation, making us tackle historically difficult-to-get-right objective functions, potentially with bad macroscopic results.
