Is the Old Testament obsolete?

I don't mean that the Old Testament is obsolete because its ideas no longer apply.  I mean that the Old Testament is obsolete because we are now living in an idiocracy where almost no one has the intelligence to understand it.  Judaism and modern Christianity have no idea what the Old Testament is about.  But Jesus and Muhammad clearly understood it.  I think even Christians during the Enlightenment (1600s and 1700s) had a fair understanding of the Old Testament.  But we seem to be living in the most stupid time in history.  This may be partly because of the dysgenic effect of modern culture.  But also because of the brain damage caused by excessive use of electronics by children.  Whatever the reason, the drop in intelligence that I have seen in my lifetime has been unbelievable, and this may well render the Old Testament obsolete.

Religions can be categorized by whether they work for smart or stupid people.  Islam, Judaism, and traditional Christianity work for both.  Modern Christianity and modern Western culture only work for stupid people.  The Old Testament, by itself, only works for smart people which is why it never produced a popular religion.  But as a part of the traditional Christian Bible, the Old Testament was undoubtedly appreciated by smart traditional Christians.  Today there is no one left to appreciate the Old Testament.  I think it is time for me to accept this fact.

The context which many prophets of Israel were operating is the complete forsaken of the Torah by the Israelites:

"The priests did not ask,
    ‘Where is the Lord?’
Those who deal with the law did not know me;
    the leaders rebelled against me.
The prophets prophesied by Baal,
    following worthless idols." (Jer 2)

In that context no one listened to Jeremiah, so eventually he was thinking of stopping his mission and complained to god:

"You deceived me, Lord, and I was deceived;
    you overpowered me and prevailed.
I am ridiculed all day long;
    everyone mocks me.
Whenever I speak, I cry out
    proclaiming violence and destruction.
So the word of the Lord has brought me
    insult and reproach all day long." (Jer. 20)

And yet Jeremiah could not stop:

"But if I say, “I will not mention his word
    or speak anymore in his name,”
his word is in my heart like a fire,
    a fire shut up in my bones.
I am weary of holding it in;
    indeed, I cannot." (Jer. 20:9)

My question to you is why is that Jeremiah could not stop?

I am not giving up on the Old Testament, or on morality.  What I am giving up on is promoting the Old Testament to the current generation who are clearly too stupid to understand it.  I will keep the Old Testament for myself and study it for myself.  And I will promote morality through Islam and related tools.

One other thing that I am giving up on is find intelligent people in modern culture.  They no longer exist, so I have no reason to deal with members of modern culture anymore, except for something like ordering a burger.  No more modern forums for me, that's over.

Thanks for your reply,

It seems I understood quite well what you said in your first post. what I pointed out in my comment - which is open for debate - is that Jeremiah, for example, encountered a generation and culture which is not much better, if at all, than the current modern culture; and despite being mocked and his suffering, he eventually continued to promote the word of god. he could not stop though it seems no one understood him.

my question in that comment was not a rhetoric question, but a genuine one. my intuition, which might be very well wrong, is indeed we should not stop promoting the OT. After all, this is how I found this site.  

(by the way, why did you return to post on Mikraite rather than "friends of Islam" ? )

Maybe we should inquire the means of promotion rather than the content itself. Marshall McLuhan once said: "The medium is the message"

"Ship your grain across the sea; after many days you may receive a return" (Ecclesiastes 11:1)

I can't judge Jeremiah's generation.  They were evil, but were they stupid?  My problem with modern culture is that not only does it make people evil, but it also makes them stupid.  And what is the purpose of promoting the Old Testament to people who are too stupid to understand it?  This is like promoting the Old Testament to barking dogs.

I gave up on "friends of Islam" because I realized that this makes no sense.  People should just convert to Islam.  Instead I just wanted Mikraite to explain my ideas to Muslims or anyone else who is interested.

I am certainly no good at marketing.  But the question is whether there is a market at all.  At the last Old Testament Discord meeting, 2 other people came and I asked them to give me just one example of a member of modern culture who isn't stupid.  They couldn't.  So I have no reason to believe that a market exists for the Old Testament.

Well, Okay.

With respect to an example, I am being lost in your definition of "member of modern culture". are you, for example, a member of modern culture? for if you don't consider yourself as a "member of modern culture", then almost by definition there are probably just very few members that are not stupid (though, that would also need deeper inquiry) . May I offer the author of the "progress debunked" book  as an example?

Today modern culture is the default.  So anyone in the West is a member of modern culture unless they follow something else.  I am not a member because I follow the Old Testament by keeping the sabbath, not eating pork, etc.  Varg is not a member because he follows European Paganism by visiting its sites and doing other rituals.  I can't tell whether the author of the "progress debunked" is a member because I don't know what he follows/does.  Ideas are not enough.  One must actually follow something else.
