That's fair enough amigo.
Your measured reply is not one to which I am especially accustomed on this topic and it gives me heart. It is my experience that any of these people, once the machinery is going, become exalted to some unimpeachable position and people cling to them, blinkered, like the proverbial to a blanket. I find that absurd.
Idle chit chat then ;-), opens up an anecdote:
In the back when I was was influenced by John Lofty Wiseman. I attended a couple of his seminars, delighted in his sarcasm and knowledge, enjoyed flat out speed of his delivery, and even copied every useful part of his first book when it came out complete with colored pencil illustrations. Absorb him into my Borg. Years later and about six months ago he showed up on TV. Here was a tired old man living happily and modestly with his wife. He opens up one of his legendary survival tins and proceeds to paw through the contents as explains them to some young urban kiddie. I described what I saw as poor value now. Time has clearly done its work on him, his tin looks crude and simplistic by modern standards, and techniques and methods have become better understood. I'm confident he'd take no insult in the observation that he may well be a bunch happier now disengaged and with his feet up in front of a TV set like a regular shnuck. I got a very hostile response for those observations something usually reserved for one that opens the little book of imaginary friends and laughs at a crucifixion. Celebrity zealots. The facts are he would not offer the same value to your team that he once did but the willfully myopic couldn't identify that. I guess that kind of thing primes me to expect willfully myopic attitudes whenever one of these people becomes exalted to guru / legend / expert status. They become sacrosanct and I'm very familiar with people digging in to preserve the status they have bestowed upon their favorites at any cost.
That phenomenon seems to be getting worse, or at least it seems to be getting worse from here. They're like celebrity Chefs; blah trained under blah who trained under Ramsey who trained under White and they all butt munch at the font of Escoffier. Then there's all the wannabes in waiting with a book for you to read or a field for you to camp in with the I have |337 skills and have opened a school 'cos I'm ex-army, designed to impress people that have never been army. Other qualifications for the would-be celebrity guru appear little more than I have lived in the countryside all my life. So what, 80 % of my friends fit in that category and it predicts little.
Not like I'd find it desirable or even plausible to set up some sort of standards framework to assess these survival gurus / celebrities but my mind seldom strays far from the fact there isn't one. There are just people earning a buck with the same array of motivations and tools as other people from the most noble to the most scandalous. The cleanest being right or wrong, but there is so much more. I genuinely feel it is imperative that this information is got out and that motivates me to snap at posts as I did above. We often hear of it being important to pass on skills to younger up and coming people getting interested in this topic as we are. If that is true then this is the most most important bit of advise I could ever offer to any of them Ignore the celebrity. Even if it should exist because people will always want a hero or a village elder, it should be fleeting and fragile. These are the people you should be trying to knock down the most because if you can't that may tell you something useful. Adoration and artificial preservation of their longevity will not. Just like a freshman in any other discipline ignore the celebrity and the pop books, read the work in the original.
Anyway mate, seems clear to me that you aren't one of the fanatics so good enough. Take no part of this as level at you, just following along the chit chat on this theme.

I think I'm now going to play the song that goes with
these lyrics that convey nicely my sentiment on the current state of celebrity. ;-)
