It is a great example of how difficult it is to anticipate the N-th order effects of things. 79 years ago the transistor was invented, in less than a century it ended up being the back back of a global surveillance system. Not many people could have foreseen this.

Cheaper computer technology has been great for the average persons uses but it cuts both ways. It also means much cheaper surveillance. I suspect that governmental/corporate surveillance now costs less than 1% of their spending, something that simple couldn't have been done even a few decades back.

I do wonder what the world would have been like is say computer technology peaked at 486 level performance/memory. Much of what we have today simply could not have happened in terms of surveillance and social media damages. Alas, this is the world we didn't get.
