This is my view too. A good portion of the people in my life are addicted to something at any given time by this broader definition. I've experienced short periods of it myself ranging from gaming to geeking out way to much on a particular topic at the expense of proper food and sleep. I see it as a result of access to an ever increasing range of pleasure induces experiences at ever lower costs and hyperbolic discounting - too much of a good thing with blinders to future costs.
