The more primitive and simple a species is, the higher its survival capacity. The more evolved and complex a species is, the lower its survival capacity. Overall, survival capacity follows a downward trend. This is diminishing resilience.
As survival capacity declines, later-evolved species increase and develop their own capacities and attributes for continued existence in order to ensure they can persist stably. This is compensation.
A rough way to understand it is that the more developed something becomes, the more complex it is; the more complex it is, the more fragile it becomes. The more fragile it is, the more it needs to be reinforced and made antifragile through substitutes in other areas.
Compensation and weakening means inverting the causality of the weakening-compensation dynamic: because humans feel they are not strong enough in some area, they compensate through external substitute solutions. Once compensation succeeds, it actually causes the weaker side to become even weaker.
We should indeed be wary of some weakening—those old skills that have been masked by substitute products but still have an important impact on our lives and survival. Humans invented keyboards; an excellent employee who transitions to a department leader can lead a team to improve overall returns, but their own skills become hard to advance further, and even their original skills may grow rusty. If something changes in the future, you may still have to make a living on your own abilities, so even when there's nothing pressing, you should get hands-on practice to stay familiar. But when the corresponding ability weakens at an accelerating pace, you should also consider whether it can be allowed to weaken, when it can weaken, or to what degree it's acceptable for it to weaken. Just think these things through clearly, so that when facing all kinds of future changes you can
With a fearless heart, act without hesitation. Weakening brings compensation; compensation brings further weakening; only by stopping the weakening can one be fearless.
