All the jobs (11) they looked at are at least medium level complexity and task delegating. They are the ones giving out time-consuming, low level jobs to cheap labour (assistants etc.) . They can save time and money by directly doing it using AI assistants instead of waiting to have an assistant available.

I am 100% convinced that Ai will and already has destroyed lots of Jobs. We will likely encounter world order disrupting changes in the coming decades when computer get another 1000 times faster and powerful in the coming 10 years.

The jobs described might get lost (obsolete or replaced) as well in the longer term if AI gets better than them. For example just now another article was mentioned in HN: "Gen Z grads say their college degrees were a waste of time and money as AI infiltrates the workplace" which would make teachers obsolete.
