~ so education based on youtube? So the Like button and subscribe is the meritocracy system? So student study based on who got the most likes buttons? Really?
Check it yourself, and then tell what you think. Go to YouTube, search "theory of evolution", for example. Although most liked, or most viewed, videos on this subject are not necessarily the best ones, you will surely find very good educational videos in the top 20. And this is also true for other subjects, not only for the "theory of evolution".
Many people treat "fake internet points" with suspicion, and in many cases they have reasons for that, but from my experience the most liked and most viewed vids are usually the most relevant ones.
Back to our topic. Do you really think that to start investing is a good idea for an uneducated person?
