The original purpose and true benefit of computing is in math (e.g. accounting), simplifying logistics, and enabling communication at a longer distance. Anything else is dystopian, socially-destructive garbage that I won't touch for the sake of my own well-being, which is why I'm not on any social media (except highly selective communities like HN or strictly for work purposes) and I strictly limit entertainment that arrives through a screen.
My yardstick for determining whether a particular pattern of use of technology is "good" or "bad" is by considering its effects on my base human faculties (eyesight, hearing, memory, physical strength and wisdom), and its effect on my relationships with others. Any pattern of use that improves my bodily faculties or my real-life relationships is good, otherwise I shun it.
