A really succinct quote from Seth on glass-is-unoptimised thinking (as opposed to cyber-optimism or cyber-pessimism, which I agree are both untenable outlooks):

Technological change doesn’t always make things better. It often comes with significant side effects and costs. And yet, thanks [to] the vigilance and hard work of some folks, technology also has a long track record of making us safer, healthier and even happier.

The cyber-realist sees both and is focused on being careful about systemic change and lock-in, especially for cultural and organizational changes that are hard to walk away from.
