AI adoption linked to 13% decline in jobs for young U.S. workers: study

I’m suss about this paper when it makes this claim:

“where AI is more likely to automate, rather than augment , human labor.”

Where is AI currently automating human labor? Not Software Engineering. Or - what’s the difference between AI that augments me so I can do the job of three people and AI that “automates human labor”

What is the effective difference between augment and automate? Either way, fewer man hours are needed to produce the same output.
