Not that engineers can't be problematic. But product people who aren't technical enough and badly manage trade offs they don't understand or invent out of thin air outnumber engineers who are pigheaded know it alls more obsessed with technical minutae than product success.
Another one I see in the same ballpark is hiring a bunch of outsourced coders and then wondering why velocity and quality goes down. (Because you're multiplying the mythical man month effect by the skill difference between a day laborer from Home Depot and someone with significant skills/domain knowledge like a welder or electrician.)
That said, the evidence on content creation and financial incentive is quite blurry - there's some relationship but there are also lots of people who create lots of things without tremendous financial incentive. And the genesis of copyright wasn't to protect authors, but publishers who had significant costs for producing first editions compared to those who might just copy a first edition.
More to the point, not every skill level or job is _worth_ that kind of compensation (as uncomfortable as it might be to entertain), and attempts to circumvent market forces by making lower wages illegal at some arbitrary point have substantially more damaging externalities than 'low wages' -- which are as much a system of slavery as gravity or magnetism, and just as resilient to ideation.
In general, though, it wouldn't matter what the minimum wage is if everyone had a sufficient level of general welfare without working...
Which goes to show that rather than minimum wage we ought to have a welbeing floor, perhaps with UBI, perhaps based on keeping key costs, like food, housing, healthcare, and education minimal.
The alternative to low wages isn't necessarily high wages. It could also be zero wages, as the study in the OP demonstrates.
But more to the point, why do these people obsessed with work and jobs always think anything that creates any kind of job is "good" no matter how bad, dangerous, or poorly compensated? Jobs that amount to licking poison for nickels in a country where you we could probably quarters the lowest currency denomination without issue somehow being "good" for the lockers is ludicrous. Low wages have massive negative externalities for society.
What I've seen with AI is that it does not save my coworkers from the pain of overcomplicating simple things that they don't really think through clearly. AI does not seem to solve this.
