Expert – It’s just a word!
There are experts and there are self proclaimed experts. To be honest I can’t understand why anyone would downgrade “expertise”.
If you go to a dentist, do you want an expert? How about eye surgery? Would you choose the village idiot or an expert mechanic to work on your car?
Would you choose Ted Williams or StarDad to teach your son how to hit?
There are those who think they are experts (lots of them) and there are real experts (not so many of them). The real experts have no problem recognizing that experts exist.
There are different levels of expertise and all experts don’t always agree with each other.
While I have never liked the word expert, they do exist. They are not all equal. For example there are some experts who post right here on this site. Anyone who has truly studied something for a long time is somewhat of an expert on the subject. Someone who has not spent that time and effort, but still acts like an expert, is just a fool. Anyone with a closed mind and who thinks they have everything completely figured out and has nothing more to learn, can’t possibly be an expert. IMO
Experts can sometimes be wrong. In fact, without ever being wrong they couldn’t have become experts. It takes experience to be one of the foremost experts.
