Don't you think that SW is waste of time, most of the time?

Eh, depends on what you consider wasteful. Sometimes it can be, which may be the point of some coming here. They need that filler that requires little commitment and brain cells. It can be a relief to just exist in that for a bit. But there’s probably better ways one could spend their time if they’re not gathering anything from the experience here. Just depends on what’s needed or wanted in that moment.
