“Then again, I’m also sympathetic: the unavoidable presence of spam in the twenty-first century not only clogs the in-boxes and bandwidth of the world (roughly 97 percent of all email messages are spam - we are talking tens of billions a day; you could literally power a small nation with the amount of electricity it takes to process the world’s daily spam), but does something arguably worse - it erodes our sense of trust. I hate that when I get messages from my friends I have to expend at least a modicum of energy, at least for the first few sentences, deciding whether it’s really them writing. We go through digital life, in the twenty-first century, with our guards up. All communications is a Turing test. All communication is suspect.”
