What was the deal with Ross? (spoilers; every post a spoiler)

[Abion47]

I'm not sure anyone thinks that Ross created Simon-2. In fact, I think it's all but confirmed that the WAU itself created Simon-2. Also, if Ross was purely digital, there are other questions that need answering as well. For example, if Ross doesn't exist in the physical realm, then what was going on with his body at Omicron? How was he talking to people, and how did he connect with Raleigh Herber? Why didn't he appear to Simon and Catherine sooner? The theory that Ross was some form of digital ghost introduces far more questions than it answers, so while I'm not discounting it as impossible, it's much more likely that he is a real being purely because of Occam's Razor (given two theories, choose the one which requires the fewest assumptions).
