Gibson could just as well have been referring to Internet security, where spammers have already polluted electronic mail so much that an entire generation has abandoned it, where phishers, pharmers, and other identity thieves are wreaking havoc, and where the old paradigm of security still seems to think it's doing a good job.
I hadn't thought of it, but my kids don't use e-mail. They are all on peer to peer chat/voice solutions in conjunction with blogs. Further, my personal response to the withering attacks on PCs (which had forced me to completely reload Windows every 6 months to a year in order to eliminate invasions), was to move to a PowerPC mac. By getting small, I've totally avoided the security problems I've had with a PC.Here's a bit of philosophy.
The more commonly used (the more ubiquitous) the ecosystem, the less secure it is. These systems represent too big a target, and they are burdened by a complexity and connectivity that makes them impossible to defend. Getting small alleviates the problem.
How small should ecosystems get? Down to the minimal level of viability (viability being defined by the minimal level of activity necessary to provide it with robustness, innovation, diversity, etc.).
How many ecosystems? The greater the diversity of the ecosystems riding on the minimal rulesets of the global platform, the more secure all of us are.
