Uber misclassifies en masse the drivers it employs and shifts vehicle depreciation costs onto these "small businesses". Our taxes pay for healthcare costs which should rightfully be borne by the drivers' employer. I would say that's a non-negligible social cost.
Some very recently published research (Dec 2025) claims evidence of fire starting among homo neanderthalensis. This would push back fire starting know-how (not only control) from 50k to 400k years ago. Cool stuff!
On the other hand, it’s odd that these “contractors” can’t set prices for their services and risk deactivation if they decline the price Uber offers.
