I love tech. It pains me to come to the conclusion that in Facebook, we have created something that should not exist: an addicative worldwide mob where peddlers can sell emotionally manipulative ideas to the people least able to handle them, whether it's clicking cows all day long or believing Elvis is still alive. In defense, I don't think anybody that was on-board at the beginning realized this. I do, however, feel…
If tech is building new edifices to the capabilities of tech, then Facebook is certainly tech, and the nightmare Facebook has become is inevitable. (Though I agree with other commenters that FB probably matters much less than we with in-built pro-tech biases are willing to believe.)
Otherwise, if tech is "doing more with less," then Facebook is extremely hard to justify as tech.
