This question already has an answer here:
Based on the answers to the question posed here, it was stated that the goal of SE is not to aid the individual, but create a solid knowledge base of useful problems and solutions for posterity.
This is a valid, and worthy goal. And, this is why redundant answers and poorly worded questions are downvoted, and closed, in order to avoid glut in the knowledge base.
However, based on the above as well as and on certain basic economics principles about the eventual pooling of value, it would seem an unintended side-effect of this would be that (considering the site is now ten years old) that it is effectively closed to new and inexperienced users.
Let me explain
Users gain reputation by answering questions, or posting good questions. In the early days of 2008, there were NO questions whatsoever (obviously) so nearly any question - no matter how basic or simplistic - were good, and received both answers and upvotes (SE recommends also upvoting the question, when a useful answer is found).
Here are some examples of very simple questions from the early days ...
These are all extremely simple questions, which have received high points for the participants based on the usefulness and how long they've been out there.
But, in 2018, nearly all of "the easy" questions have been answered. Any questions even remotely similar to the above would be both immediately closed as redundant, and downvoted to very low stats (affecting the reputation of the asker).
On the flip side; "harder" questions are, of course, still valid and gain a lot of reputation for users. But inexperienced users cannot answer these questions. So, again, no possibility of reputation points.
As a user who deeply values SE, and is somewhat concerned for it's continued success...does this mean SE is effectively now a closed community? And how will this affect its future?
