Well....
After some time to read/skim the various posts - I don't think I have a whole lot that I can add to this discussion that has not already been said.
mjc has stated his position and beliefs, and other people have contributed.
I, personally, do not subscribe to this "computer generated" notion of "reality." I would be more willing to put my money on "This is some other being's DMT trip or dream" than "this is a CGI simulation."
However, it IS a simulation. It's a simulation of what would happen when the universe
happens. I don't think it was carefully scripted by a sole creator. Sure there are a few lone wolf programmers and coders, but most work as a team. Collaboration with each other to see if the other person knows how to overcome an obstacle. In the case of the universe, it is scripted by the molecules and atoms. (which are scripted by smaller and smaller and smaller..... bits of mass.)
Yes, I've had psychedelic experiences that have left me imagining that reality is an expression of a very complex series of wave functions that have been crashed from their wave form into a series of particles. From there, they orient themselves in a seemingly infinite number of different positions and arrangements. They form these constructs, bodies, that we use to express ourselves. Maybe the molecules are the sentient ones, and our idea of consciousness is a joke? Without their orientation, there would be absolutely no "body" to hold a soul. But, they orient themselves based on conditions. Conditions which have been ever changing....
I try not to get too hung up on the human models of interpreting the universe and reality. Humans desire models so that they can explain the "uneasily-explained." This is a process that has occurred time after time after time. An example - look at the early models of the atom. Look at how much the models have changed. They have changed to match the "observable." So, to imply that reality is a simulation also implies that you limit the simulation to a model. Currently, your model does not have supporting evidence that matches the observable. If substantial data can provide a reproducible means to test this model, then it would be something that is widely discussed throughout all off the "flesh machines." (Even the "CGI robots" [shoot, they'd/we'd be happy, because then they/we would have that awareness that you say that they/we lack.)
I don't think a model can describe what's going on. Not any human (or computer) model. And, you already know my feelings from our exchanges in chat - I have many favorable theories about this thing. But, they are all theories. One, or all, of them might be right.... or one or all may be wrong.
My favorite theory is that the "universe" is just trying to experience itself in as many/or all subjective ways possible within the limiting and physical restrictions. Our constructs are just one of the many ways that the quantum weirdness expresses itself. Maybe it's not too different from some of your beliefs, but I feel like you apply too much emotion into these beliefs. I don't mean emotion like "love" or "hate" - but a fear that you may be wrong. How do you feel about being wrong? Are you comfortable admitting when you are wrong? Would you be willing to admit that you are wrong if there were to be some sort of unified observable data that would prove your theory incorrect? I only ask, because I know that I am wrong quite often. By being wrong, I my feel disappointed in myself, but I am also opening my mind to learn something new.
The fear of being wrong causes many people to commit to beliefs - even when the beliefs are not supported with rationality and only considered from subjective views. We see it throughout every single religion. All religions claim an absolute --- which leads one to think that maybe none of them are absolute... or even close. Maybe they are so far from the truth that they can't even imagine what truth is?
Unfortunately, that is how I feel about the CGI robot theory. I cannot confirm your theory. It might be a possibility, but it might not. There are a lot of "mights." There are too many "mights" for me to pick one, and as far as I am concerned - I've never been obligated to pick! People may tell me I "should" pick, but they have no authority over my choice.
In ways we're similar - you're convinced that there is an absolute; and I am convinced that "there could be an absolute, but we've got no way to know." - basically, there is no absolute. I know that out of body experiences and the "aha" moments can feel empowering. As mentioned, I've had many theories and many "aha!" moments. But, they are moments. Fractals of time within time. And once they've passed, then they've fulfilled their possibility of existing before submerging into the abyss of existence.
Personally, I think you should stop worrying about WHAT "reality" is, and focus on just doing it. I am sure that people have said this in previous comments. No matter what it is, we're still gonna be doing it until we aren't doing it any longer. Who cares if some bearded dude in the clouds made this place, who cares if it is a computer, who cares if the crazy space aliens made human beings as a science experiment.... Those things ARE the distractions. Fixation on a singular concept blinds one from seeing all the other possibilities. Focusing on one concept robs you of the joys that may come from learning and exploring new ideas. It's fun to entertain such thoughts, but when they become obsessive, then you're only cheating yourself out of the pleasure within..... what ever you wanna call this life.
Personally, I'd drop the absolutes, and just love your lady; find a hobby; start producing art; anything that allows you to express your feelings. Shoot, write a sci-fi book about the CGI reality and your perspectives. The rest will fall into place once you stop trying to put cylindrical pegs into triangular holes. One size does not fit all. LOL
However, you can use love to fill any hole.
It changes shape so that it can join those who wish to experience it.
Happiness can fill any hole.
Fear can fill any hole.
Hate can fill any hole.
When people have a void – such as the feelings associated with existential crisis/questioning, they want to fill that void with something. They will often fill it with an emotion and idea. The voids are created from temporary awareness of our true ignorance. Once we're aware of our void/ignorance, we try to fill it with a model - piece together the gaps. This construct can be a result of many things - such as social activities, musical preference, art, hobbies, TV shows, conspiracy theories on the internet..... and it goes on. So, people say, "Oh crap, I DON'T know what I thought I knew. What is the easiest answer that creates the least amount of cognitive dissonance?" --- NOT! People don't say that! or think that! they just do it. Without thinking. People will use their immediate influences and construct a mental model to easily fill the gaps that have been created from moments of temporary awareness of our true ignorance.
You asked me to reply, I did. It may not be what you were looking for, but it is what has found you. I told you it would be when the time is right. Is this the right time?
***Looks to the right; sees the clock on the oven***
Yep, it looks like the time is right.
You know I love yah, mjc. I hope you don't take my words as negative criticism. I wanted to convey my perspective and do so in an honest manner. It's ok to have disagreeing beliefs about these ideas. Healthy communication and collaboration helps us move further away from ignorance. When one closes their mind off from being able to learn, then they are accepting ignorance and accepting a constructed model, from which their own mind created. Upon collaboration, then the model can be proposed. After speculation and thorough investigation, it is either accepted by the consensus, or the idea is rejected. In my opinion, a singular person cannot construct a model that fills the void that has been created by the mystery of the universe. If they can, great! What are they trying to prove? To who? Why? And then what?

Take Care,
