Unless you're an important person, celebrity etc, your email is not worth reading, hence under the context, there aren't people out there reading everyone's email. Proportionally, there wouldn't be enough time in this world for people to read every email of every person. Again, you have to look at it under the context of email having a common denominator property of each and every individual on this planet earth, just as, the post office mail box belongs to each and every household. Assume you can read my email and I can read yours, both of our email content would be intelligible and useless for each of us to waste time on.
Ultimately, the point is not if a machine or human is or can read email....the point is, whether present day civilization should give up this privacy aspect to machines/corporations/government etc. The answer is already obvious, somebody has to manage the technology and that somebody is most likely not you....so by default, you have given up your privacy to someone else, so it can be managed for you.
The more bigger and unresolved problem is whether government or corporation should use machines to profile each and every one of us to preempt potential criminals.
