That's a bit too cynical and missing the point. "Content" is what people want. You create what people want.
You should be writing essays, recording tutorials, training, music, conversations, etc. the kind of things you care about, for an audience whose attention you don’t take for granted, hoping that they too will care at least a little. If they do, they will pay you because they will rather part with money than part with your work.
Yeah, that's called content. "the kind of things you care about, for an audience whose attention you don’t take for granted, hoping that they too will care at least a little" doesn't quite roll off the tongue.
