One of my favorite counterintuitive examples: The biggest economic gains from the 1800s Industrial Revolution actually came from the humble washer/dryer. By making routine homeware 100x more efficient, this (along with other home appliances) allowed more women to enter the labor force, nearly doubling labor force participation within a couple generations. Though, at the beginning, lots of people were opining about homemakers losing a sense of purpose or relaxing all the time.
It's certainly possible that this study is just reinforcing the researcher's biases from their previous understanding of the economics of innovation, and also possible that this study is accurate today but conditions will change in the future. That said, I believe the burden of proof is on the pundits claiming cataclysmic job loss, which is counter to economic historians' models of innovation.
