I think surely internet is good thing when complimented with books,when i say books i mean like campbell biology,jd clayden chemistry,feynnman physics like these,we have plan ,but on internet everything is random,i can bet no one who rely on the social media,and popular edzy video would be able to do 1 percent what a nerd is capable of,isnt it?

You are applying an unfair filter here. As I said above, there are millions of garbage books out there too. You can find books on any subject that say anything, including that fasting is healthy and kills cancer.

But you only count good books as books, but you don't apply the same filter to the internet. Same as with books, there's garbage on the internet, but there's also great sources on the internet. Media literacy is required for any medium to discern garbage from decent content, and anyone needs to know how to find good sources and how to do proper research no matter which medium you use.

On the internet, finding sources is at least much easier than in books. If a book cites some other book as a source, you need to go to the next university library and hope they happen to have that book in store, otherwise you are often SOL. On the internet, most sources are readily available or at worst behind archive.org.

The things is state,nazi,brahmins or whatever ,these people commands lots of power of flow of information on internet ,you cannot stop their propaganda online.

Yeah, but that's again the same with any media, including books. Remember, the literal nazis had very advanced and very successful propaganda, and there was no internet in sight back then. "Mein Kampf" was a book and it was everywhere in Nazi Germany. "Die deutsche Mutter und ihr erstes Kind" was a parenting guide book that was given to every mother in Nazi Germany, and the horrific parenting "tips" in there messed up multiple generations of Germans. Books can do just as much harm as any other media.

Entire reddit is filled with pseudo intellectual garbage,we have twitter pure filth,then other platform like insta facebook. You cannot learn much from it other than general facts which can be wrong as well.see long story short internet doesn’t teach you temperament. Its just a bad place for learning tbh

Wikipedia has baseline knowledge for pretty much any topic. University websites freely share research papers. Tutorials on pretty much any topic are all over Youtube, blogs and other sites.

Want to know how to repair your washing machine? Good look on finding a book on that, but there's a Youtube video for your exact model right there.

Want to know the specifics for some obscure camera control protocol? Sure, right there on some random blog, or you can just download the original specification.
