I have several problems with this statement, starting with the fact that it was derived from a rationalization of the author's own habits, not a meaningful empirical observation.
Further, this is a formula for addiction. Games, porn, gambling, food cravings and drugs are all similar in that they self-enforce a habit through perceived short-term rewards.
Self-discipline is what allows one to accomplish goals. And, it means adapting your brain so that it can supress these hormone driven urges and take action that measurably moves your progress towards a rationally derived goal.
I'm all about some R&R, and fun / entertainment / addictions all have their place. Personally, I become a gamer for about 1 month every 2 years. I even think this author probably has more self-disciplne than he lets on judging by his writing and the history of games he has created. However, the message this article conveys is destructive.
Rationality and self-discipline use a different part of your brain than cravings for short-term rewards. Before you rationalize a time wasting habit, make sure you have adapted your mind to have the self-discipline to switch back and forth. Some people with particularly addition-oriented genetics really should fully abstain from mind-whittling activities if they want to accomplish anything in their life.
My point of view also assumes you are someone who wants to accomplish some substantial goal(s) in your lifetime. If you choose to live a lifestyle of fun / bliss, by all means, whittle away..
Its just a reckless way to say 'we all waste time..' - not without making the distinction of the need for self-discipline and noting that there are some people that are very prone to addiction. I have an extended family member who's life outside of games has been completely destroyed by a sustained addiction to video games. He has stated repeatedly that he would rather be dead than give up gaming.
This is a real problem for a percentage of the population, and that percentage is increasing as video games are being engineered to be more and more addictive.
Anyway, in one of those half asleep dazes the other day, I swear I caught my brain 'compiling' or 'defragging' or something. I could feel my eyes doing REM, and I could see or sense a whole lot of information I'd been studying being chunked, parsed and filed away in a more appropriate part of memory. Of course, that itself was probably just a dream...
That might be your brain telling you to switch to a task that doesn't involve one of those activities for a day or two. :P
Another explanation could be that the precursor to grinding in EQ is the urge to do things like searching for edible plants or animal tracks, carving tools, cleaning the home, and other things which have obvious evolutionary benefit.
This has been known to science for at least a century. The slightest glimpse at Wikipedia would have sufficed.
The different is that Jeff gives an argument for why somone would whittle instead of just lazing like a lion or a dog does. Whittling is (slightly) more rewarding, but sleeping is more energy efficient.
