No, it's not paradoxical. You are conflating time points.
I won't debate the "value" of CEOs, but in this system, their value is subject to market conditions like any other. Human computers were valued much more before electrical computers were created. Aluminum was worth more than gold before a fast and cheap extraction process was invented.
You could not replace a CEO with a Palm pilot 10 years ago.
Buddam tsssss! I too enjoy making fun of big business CEOs as mindless trend-followers. But even "following a trend" is a strategy attributable to a mind with reasoning ability that makes a choice. Now the quality of that reasoning or the effectiveness of that choice is another matter.
As tempting as it is, dehumanizing people we find horrible also risks blinding us to our own capacity for such horror as humans.
