The Mandela Effect is the greatest thing to ever face humanity and people ignore it, why?

I have mentioned the Mandela Effect to multiple people, quizzing them and they remember things the old way and get it wrong and say no way, and I prove it to them by showing it to them that it changed, and they go wow. And from then on, nothing.

When I first learned about the Mandela Effect I studied it for days and weeks, I tried to find out all the instances I could recall, I asked others if they remembered the same things or different to verify and validate what I had discovered and to also help me stay sane. Surely others remember the same thing?

But when I mention it to others, they get a glazed look on their face and agree with some but I never hear about it from them ever again.

Nobody ever comes to me with a list of Mandela Effects and asks have I heard about this one or that one.

None of them become avid researchers asking for all the ones I know or more.

None of them really bring it up ever again.

I have heard multiple people say that this is the same experience they have had and they are surprised by how few people seem to care about it or acknowledge it.

What do you think the reason is for this?

The first thought is we are living in a simulation and they are NPCs because a real human or entity would care about something like that. It's the biggest or greatest thing to ever face humanity.

There are changes in the Bible now yet none of these church going people are acknowledging them or talking about it or researching it. Why? How is this not discussed more often everywhere?

In my lifetime I have never had anyone come up to me telling me about the Mandela Effect or examples, it seems to always be me telling others and sometimes they already claim to have heard about it.

Is this how you can tell who is real and who is an NPC? By their ability to hold memories outside of the simulation? It's like the hard drive and only some noticed because they are operating outside of that hard drive with an actual memory but NPCs can only operate on that hard drive.
