#cybersec seems to be a valid argument, on first impression. But I don't buy it. The approach seems to inteoduce with every solved problem, a slew of new ones. The #targetsurface seems to be increased, instead of decreased. A fractured system is harder to breach than a single entity. While I can imagine sub-systems mitigating these issues, the history of the industry doesn't awaken confidence. Add to that the issue of inivitably creating monopolies. /3
