The modern human nervous system is the result of upwards of a hundred thousand years of brutal field-testing. The basic components, and even whole submodules, can be traced back even further. A certain amount of resiliency is to be expected. If you want to start from scratch and aspire to the same or higher standards of performance, it might be sensible to be prepared to invest the same amount of time and capital that the BIG did.

That you have not yet been crippled by a moral paradox or other standard rhetorical trick is comparable to saying that a server remains secure after a child spent an afternoon poking around with it and trying out lists of default passwords: a good sign, certainly, and a test many would fail, but not in itself proof of perfection.
