Driving is just a gig, it's not like they are super invested in it and did years of study in a particular style of driving and couldn't do any other job. The apathy is because it's easy come, easy go.
It seems to me more like funnelling money from investors to software developers and consumers given how unprofitable they are.
So I don't see traditional jobs being cannibalized for the most part.
Alternatively, wages are low in gig apps because so many enjoy the flexibility that the apps provide.
