Apologies for dropping offline shortly after posting this. :(
I should say that I enjoyed this post. And I think leaning into that confusion is my aim. In particular, my point of stochastic versus random is that they are more synonym than they are anything else. Just words that different groups came to use covering similar things.
Which is not to say that their aren't differences in the crowd that uses each term. I posit that most of the differences is in the aims of the crowd, and at the end of the day, you can get a lot of mileage by embracing the similarities. As opposed to the default of contrasting on the differences.
As a fun example, to me, if you view time not as just a number that always goes up, but as a number that cycles through the seasonal values, then it is easy to view as most any other feature. Similarly, the past is easy to envision as a feature of the present.
I do think the way you described a lot of time series analysis fits the fun read I had where Mandlebrot proposed a fractal view of time series predictions. Where you are looking for self similar behavior in the series data and reflecting/overlaying it on itself. But... as is probably guessable from the rest of my post, a lot of this is far outside of my comfort area. Love reading about it from a distance.
