A healthy economy is a lot like a healthy ecosystem: some parts are weaker, some will fail when stressed, but allowing the system to react naturally to inputs will likely result in a better outcome. But when you encourage a monoculture, single stresses can result in a complete collapse[2]. We're experimenting with establishing monocultures in our economies with potentially even more impact than those of the 19th and 20th centuries (like Standard Oil) that inspired the anti-monopoly regulation and legislation: if Samsung were to shut down tomorrow, what would be the impact on the Korean, regional and world economies?
An all-powerful Google that can't accept criticism or action to "trim it back" to preserve the overall economy represents a danger and Mr. Lynn was right to point this out.
