Say, let’s admit consciousness is the result of a physical process.
Then say this process only goes “forward” when our time coordinate increases. Just like an egg gets cooked when it’s temperature coordinate increases, but it doesn’t get more or less cooked when it’s temperature coordinate decreases.
This would mean that going back in time doesn’t result in any perceptible change, since your consciousness hasn’t evolved from it’s “former” state.
Thus making it possible for us to be travelling through plenty of dimensions in varied directions, only ever experiencing the brief times when you happen to be moving in increasing time. Or whatever combination of movement along varied dimensions makes it possible for you to be conscious.

Useful to what end? The very idea that you need to build a model is based on believing in a system that thinks the model is important.
A model is an understanding of how it works. It allows one to predict how things might react in different general cases, which can be very useful for innovation. You don’t need to try understand things if you don’t want to, but it’s a bit ignorant sounding.
“Models work because they help us make better models, and we know better models work because… they’re better models.”
I think maybe you misunderstand what a model is in this context. It’s any way of mapping observations to a theory of how things work. I would say a good model is one that can create useful testable predictions. This tests the accuracy of the model, and it also provides for innovation. You can have a model based on a random sky fairy magically doing stuff and writing a book about it. But that model is untestable, and useless.
