They say consult an expert before trying something dangerous. What expert? How did the become expert? Who was the first expert? You mean somebody with no experience at all did something and became expert? Then why can ANYBODY do ANYTHING and become expert at it without consulting an expert? Why should anybody need a license, anybody can train themselves and become expert. Or is it really a protectionist scheme to keep others out.
Usually so called "experts" are the ones who pay for some certificate that says they are an expert or they have other people call them an expert(and they then call those people experts too).
I doubt you'll find to many real experts around but just a bunch of people with ego's that *claim* they are experts. A true expert has no need to call himself an expert.
Probably the only expert I have seen on this NG or other's involving electronics is Winfield Hill. There might be a few others but the rest are just posers that have some need to try and get other people to think they are smart.
Much ot the time, people actually like "experts". If someone is certified, that means the person seeking the help doesn't have to bother with evaluating the information, they can just follow what the "expert" says and if something goes wrong, they can say "but I followed the expert".
People ask questions here all the time, and they don't have any means of evaluating the answers. It's not that they need "experts' it's that they need to be less lazy and do some study themselves. The fact that people ask common questions here suggests they aren't bothering with books, which often are more focused on providing understanding rather than an end solution.
And sometimes it can be really amusing. Someone asks a question, and since they have no background in the subject, they'll follow any answer that gets posted. But then when a different answer comes along, they'll veer off in that direction, until yet another answer comes to steer them off in a third direction. It's not that the repliers are steering them wrong, it's merely that the original poster can't evaluate the answers, so they have to take any answer literally. Unfortunately, the repliers often take the questions too literarally, answer the question rather than evaluating the question to try to determine what the poster is really asking.
The August 2006 Scientific American had an interesting article called "The Expert Mind", which suggests that it takes about
10 years of total immersion in a field to become an expert, whether it be chess or soccer or whatever. I suspect that this is not really a remarkable claim, since very few people devote that much energy to a single field, so the few that do will be at the top by default.
But it does seem to confirm that the "secret" to becoming good at anything is that old tried-and-true approach... practice, practice, practice!

ex means "has been" .. or once was or past ... pert means "lively, sprightly, in good health .. bold, forward .. skilled" ... so that an expert is one who has lost the innate intelligence of their childhood.
in other words .. an ex - spurt could be said to be a "has been .. an unknown drip under pressure" ...
