Interestingly, human society is also a system that has been hugely impacted by sudden innovations increasing the production efficiency, each leading to an observable redistribution of power.
So, will the best performing companies 10 years forward be the ones flattening hierarchy as much as possible?
Now I don't see how flattening hierarchy could cure this. Decisions must still be taken for example for utilities and any other complex system and people must work so we need role shifts and we need process changes effective and apparent for organizations otherwise thay won't benefit and suffer from the shock.
The analogy with COVID was also a kind of what if: could we have an economic confinement if efficiency gains are collapsing the economy ?
But it does not remove the horizontal coordination that high-stakes changes require (legal, finance, security, etc), so in a sense I agree, it doesn't totally cure decision making DDoS, but it helps.

The COVID analogy is interesting, so your assumption is that companies will struggle to make profit because they'll operate changes to handle over-efficiency and these would lead to high financial losses?
