Assuming people don't realize they could have spent that time doing something else is pretty pretentious. Even people who do all manner of productive things need some down time. Pointing out certain things @tygxc says are wrong is very low hanging fruit, which is to say it can be done recreationally with little effort or thought. Assuming otherwise is also pretentious. Not reading much of the topic to know this is also pretentious.
I've attacked this topic, but on the basis that it goes in circles.
Anyway, the person's critique is is not very interesting. It's only superficially true at best, and generally whiny.
The whining here is in your post, where you complain about this feeling I'm being pretentious and condescending to you. That sense of pretense you are picking up on... it is related to a looming castration anxiety that you have. You feel it when paternal figures presume to correct your behavior. There is nothing I can do to minimize this, short of just not pointing out the problem. But I'm not going to refrain from pointing out this problem. The correct way for you to respond to that feeling would be to just admit the error and correct it. Which would be very good for you. You could say this would be you... taking the heroes journey. It could have profound and far reaching positive effects if you responded correctly... but no, you don't want to do that. So instead you come up with these stupid criticisms that just reinforce your existing failures.
Some simple math would have disabused you of your notion. 2.5 years of 100+ posts every day (the thread has been adding at least 2 pages a day of late, if not 3+) would come out to about 73,000 posts. There are 13,000 posts here.
It's making an assumption to generalize a specific rate, but even I grant it's consistently 100 a day - we're then talking about almost 4.5 months of continuous daily posting in this thread - typing out detailed rebuttals, which often takes a significant amount of time. And that's just on this topic... That is a giant waste of time.
Great defense - you sure got me. People in this thread didn't waste 2.5 years debating, just 4.5 months of continuous debating spread out over the course of 2.5 years! Oh man you really got me.
If you did skim the thread instead of making an assumption, you would quickly discover that the thread goes through periods of activity and then periods of non-activity. Not unsurprisingly, the periods of activity correspond to the times when crackpots start making ridiculous claims.
To waste months of your life debating a topic like this, to make 13180 posts on it, is crackpot behavior.
As for people's lives...I consider several of the activities you mentioned previously to be a waste of time at this point...
I find it completely predictable that you would claim other activities such as carpentry, meeting your wife, working on chess, etc. are indistinguishable from debating some pointless topic on the internet. It's predictable because it justifies your behavior, and that's just exactly what I can count on you doing. That's how you got to this point. I wouldn't expect someone with the ability to introspect to wind up debating for 4.5 months continuously a completely useless topic like this. But in reality... all the activities I mentioned actually have some intrinsic value, whereas squabbling over the internet with randos to prop up your broken ego... doesn't have much intrinsic value. No, I'm afraid it doesn't.
*but*, unlike you, I would not be so crass as to try to tell others that they are wasting their own time in a life where they have free will and choice
Of course you wouldn't point it out to people, because you don't want anyone pointing it out to you, do you?
especially while "wasting time" in exactly the same manner while decrying the practice.
It's not in the same manner, due to the scale and nature - for starters, if you were to heed my advice it would actually be healthy for you, whereas your debate topic is just some completely meaningless squabble over tablebases that has gone on for 4.5 months. Secondly I have no intention of spending the next 4.5 months here with you addressing every one of your predictable, lame excuses for why you're justified by wasting 4.5 months of your life in an online circle jerk. That's the key difference.
You know what humans are good at
Making useless things magically useful or important
