1) As has been shown time and time again, the rewards of productivity gains accrue to the owners of capital far more than to the workers who are more productive. The result is widening inequality on many levels, which extrapolated a few decades into the future ends up looking... not great. I hope we can agree that de facto serfdom is a bad thing.
2) You can't just look at the number of new jobs when making employment generalizations - you have to look at the quality and type of jobs that were created to replace the ones lost. It's like if you took away someone's house and then gave them a tiny apartment a year later, then claimed "Look, they got housing back! Everything's great again!". In the case of employment, the vast majority of jobs created in the last decade have been contract positions and low-end temp work [1]. If you look at the sectors where employment has grown when new jobs data comes out, low-end service jobs continuously top the list (ex. [2]). We can debate whether or not people actually want these types of new jobs as opposed to traditional real estate/financial services/salaried construction/etc. jobs that were lost in 2009-2010.
3) We haven't hit the automation crisis yet in any meaningful way. When autonomous trucks and warehouse robots become prevalent, then we will be in an actual crisis.
The automation crisis right now is not that everyone is going to lose their jobs overnight, but that automation is exacerbating big problems in the jobs market that lead to massive inequality, the prevalence of underemployment, and the trend towards bad jobs with few or no benefits and workers needing to work gigs on the side to make ends meet or afford the things that their normal job would have provided in decades past. When large swathes of workers lose their jobs to automation in the future, these problems are going to continue to compound unless we start making big policy changes. Yes, people will likely find new jobs to replace the ones lost, but will they actually be better or worse off than before?
