If the agent swarm is collectively smarter and better than the SRE, they'll be replaced just like other types of workers. There is no domain that has special protection.
I actually argue that AI will therefore impact these levels of management the most.
Think about it, if you were employed as a transformational CEO would you risk trying to fight existing managers or just replace them with AI?
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.
AI will transform this.
At all large MNCs I worked at, management got hired and fired mostly on their (or lack thereof) connections and less on what they actually did. Once they got let go, they had near impossible time finding another management position elsewhere without connections in other places.
I wonder if capitalism and democracy will be just a short chapter in history that will be replaced by something else. Autocratic governments seem to be the most prevalent form of government in history.
Edit: Or maybe he is fully aware and just need to push some books before it's too late.
