I suspect we have been teetering on that "tipping point" for some time now. ALL of our systems are vulnerable. Witness recent events. It appears that a single computer error can disrupt or even shut down air travel. Health care has long since become indistinguishable from pharmacare. Education has been replaced by indoctrination. Most 'western liberal democracies' are well advanced as they work diligently to eliminate the nuclear family. We can no longer guarantee a reliable supply of water to much of the population. The "information age" has degenerated into a to-the-death contest for what is left of the minds of the populace. Not only will this not end well - it may well end soon!
