By the time you have accrued detailed experience of how both these technical systems and social systems work, you may be well on your way to understanding how the world works (in abstract, at any rate)?
The author describes the phenomenon, but doesn't seem to see the broader picture. This is where a meta-systematic, or paradigmatic (if you're allergic to the word 'meta') perspective is needed, which transcends both social and technical systems, but appreciated how they fit into a larger scheme.
Through this lens the world is decidedly pluralistic and cannot be condensed to 'it's like X, we gotta do Y'. That can work for a personal strategy, and the author is kind enough to make some suggestions, but it's intellectual overreach to try and label the world
"Social engineering" is just dystopian newspeak for "deception, manipulation, lying, and bullshitting to get what you want". If honest language were used, maybe it wouldn't look so sexy.
Anything else that avoids immoral means is just a matter of rhetorical skill and ability to negotiate.
