I disagree. In fact they’ll be the FIRST to be replaced, as that is the richest target for replacement. Think about it. You wouldn’t build a robot (R+D costs) to do the job of someone cheap unless you can build many many robots and amortize the cost over millions.
Soldiers for instance are EXTREMELY expensive; so in modern theaters they’re being replaced with drones and missiles.
And executives are being replaced with automation in that there are less and less of them and the ones that remain have much higher leverage.
