Re:Efficiency is dangerous and slowing down makes life better

I think you're both talking about different ideas here. Efficiency is good. But redundancy is also good (necessary, even, for a resilient system), and the problem is that you can always increase efficiency by removing redundancy, so it does get removed by short-sighted efficiency-optimizers.
Topically, in the past week we've seen two giant companies, Adobe and Canon, lose unimaginable amounts of user data. If they had had backups, which are a form of redundancy, this would not have been a problem. But the backups were too expensive--too inefficient--and so now customer trust in their service is absolutely destroyed.
Cache/reserve and efficency is itself complicated and situational if it helps or hurts efficiency. Overfitting it could make it fragile but it also depends upon relative costs for what a blind pursuit of efficiency goes for. If something is cheap enough like data storage there will be plentiful slack because slimming it down is irrelevant to efficiency - why bother going with custom 4KB chips when economy of scale means a 250 MB one is cheaper and better? It just isn't worth trying to cut corners there.
A laggard damped system would take longer to get into a "bad state" assuming the environment doesn't demand rapid changes as the baseline to survive. Bad state is relative as always - one can doom themselves both by leaping onto the "next big thing" which isn't and by sticking to the buggy whip and musket when others have cars and automatic rifles.
