'security experts' would be unemployed if networks were made secure.
When we discover that the real solution to the problem we are working on will put us out of work, we generally will select an alternative way to address the problem that will not.
For that reason no one who derives an income from their real or supposed expertise in 'computer security' is reliable, despite their expertise.
Google Faceblather and every other cult company requires as part of their business model that the internet be an insecure and dangerous sewer so that their portals seem attractive by comparison with their promise of (partial/conditional) security.
In order for us to cross the complexity barrier, and enter upon the next phase of being, we need to purge the pedovore cultist lies and filth from our circulating information supply.
Insecure corrupt and polluted information systems will not support an advanced computational civilization. If these are not repaired or replace ours will collapse and we will regress to a cultist wet dream slave civilization.
We have a system now where lies are retained, recirculated and compounded with new falsehoods and as a result new erroneous conclusions reached.
This decades long destructive feedback process is common to all information processing systems, whether biological, as we are, or silicon as our devices are.
In silicon computation this deliberately process is called a "database integrity attack" - in which errors are inserted deep in a database, and when called up for use in a calculation, produce errors of ever increasing magnitude -depending on their distance from the calculation.
John von Neuman mentions this property of all information processing systems in his final, never completed, work The Computer and the Brain.
Given this book and his interest in the mathematics of weather systems, JvN was on the verge of an even greater discovery, that the universe is conscious.
