Simply put, it's great! It is free information that even AI chatbots use for training. Reliability of Wikipedia
However, there is a bias that because it changes, it's not good. In reality, some bots prevent spam emails now, most pages are locked, and it also remains up-to-date (unlike printed encyclopedias)
Obviously it has changed now. Tech usually faces scapegoating before it becomes
well-established.
I theorize people with superiority seem just hate it when they expected
it to be total chaos, when Wikipedia turned out sucessful!
