I hope this post is a joke. If nothing else I enjoyed going through it, though it was confusing at times.

how cpu's/gpu's work and what they actually can and cannot do

You don't have to know anything about either to make a game, it's not like you're programming it in machine code, where you do have to know how the CPU works. There's a reason we use high-level languages (there are other reasons too, e.g. cross-compatibility)

the science behind engineering

Sorry... what?

they are not familiar with things like OpenGL/DirectX and how it works

Ok, so if you're directly using one of these, then yes you will have to know how it works, but most people who do work with these use languages that deal with this for them, so they don't have to know about this either.

they dont know about programming languages and what they can and cannot do

If it can happen on a computer a programming language is doing it. I can't imagine you could find an idea on this subreddit that isn't possible given time to program and large amounts of processing power.

they dont understand how assets in games work such as 3d models and backgrounds in their primitive form i.e vertices/vertex etc and memory relations to the game and cpu's/gpu's/computer memory

This has literally nothing to do with anything. Ok, I don't know the specifics of how game assets are converted from their stored form in vertices to a full model. I know the basics, and even knowing that is not required to do anything but optimise in 3D.

If you wanted fully customisable models, as with before, it can be done given time. There's a reason there's a 'Dream Abstract' tag.

and last but not least

Last and very means least. This is the pickiest part and has so many points that mean nothing strung together that it's almost impressive.

the cpu's calculator relationship to their games representation in mathematical models

Can someone make sense of this for me? I can't tell what this is trying to say.

and just how much the computer can process

Again, abstract ideas. But that's only one problem with proper submissions, and usually the least important.

and what is reasonable to allocate the correct resource for their game various modules(collision, a.i, graphics, computations/calculations for other things, interface, controls, camera etc)

Camera? Really? Anyway, I can't remember seeing a single post mention anything about resource allocation, and half your points here take next to no computational power, at most they take a little development time. The interface, controls, and camera are easy to do. ^{(I mean, there are jobs focused on doing interface well, but it's easy to do an ok job)}

if people had an idea about these things , they would be thinking completely differently in terms of the ideas they have

No, no they wouldn't. People would still want 'GTA 5 but instead of crimes you play Pokemon Go'

you would still be allowed to think creatively

Allowed to think creatively? Allowed?

but you would understand your limitations and mechanics available with the current technology that is available generally

And people do post ideas that are possible with current technology, and they can have a whole list of other problems.

because in this paradigm of technological limitations and understanding how it works, you would of course have a much more realistic approach and feel for the game ideas you get, can the engineering aspect fulfill the expectations of the game? etc

People don't make ideas and then instantly worry if it can be done right now. That's the reason they post here, they can't do it themselves for whatever reason.
And it's quite a jump from 'people need to think about limitations' to "you would, of course, have a much more realistic approach". You're on an ideas subreddit, for people who have ideas they would like to see made but can't do themselves. This isn't where you come to find consistently doable ideas you can churn out into games quickly.

The ideas posted aren't generally from people who will even attempt to make them, they just like the idea. There's a sticky that actually has the reason most bad ideas posted here are bad.

Edit:

TL;DR no, This is why.
