I suspect the work you're talking about could be easily handled by an intern working with Core ML and a MacBook. The landscape is varied. There are companies doing real actual big leading edge stuff, there are companies where ML is sprinkled onto projects as a buzzword but no real interesting work happens, and companies that just need a practical small solution like the ones you mentioned, and could get by with Core ML, but don't because they hire a PhD who isn't aware of Core ML.
