>I actually argue that AI will therefore impact these levels of management the most.

Not AI but bad economy and mass layoffs tend to wipe out management positions the most. As a decent IC, in case of layoffs in bad economy, you'll always find some place to work at if you're flexible with location and salary because everyone still needs people who know how to actually build shit, but nobody needs to add more managers in their ranks to consume payroll and add no value.
