Scale, rate, time, and distance matter.
Fundamental changes to these, matter. Even small ones. Especially big ones.
Moving the needle a few percent (or fractions of a percent) can be game-changers in business or politics through threshold effects.
Moving the needle by orders of magnitude is effectively an entire new physics regime. And that's what we're seeing here.
Just because Y is "the same as X" doesn't mean that Y is X, if the rate of change is 10x, or 100x, or 1000x, or 1,000,000x greater. A 10x change gets you from walking speed to a car. 100x is an aircraft. 1,000x is an ICBM. The Tsar Bomba is Greek Fire ... at scale.
Infotech advances change costs by factors of millions to billions, far outside the scales above: ICBMs compunded, several times.
And such changes have massive unintended consequences.
Information technology is the perception and feedback system of society as a whole. Changing properties of information perceptibility, parsibility, storage, retrieval, processing, and distribution of information fundamentally changes entire social orders, and often not for the better. Lowering costs makes marginally "profitable" -- often in the rents-extracting sense -- applications more tractable. In that context, religious and political propaganda, yellow journalism, advertising, noise pollution, popular demagogues, urban legends, email spam, robocalls, stalking, harassment, pseudoscientific myths (flat earth, antivax, truthers, birthers), media (social or otherwise) smear tactics, and automaded extortion are entirely predictable outcomes.
