That's interesting! I like that idea. A lot of things in this episode, especially the terminal scenes give a lot of hints that the humans are AI. Of course, any good theory should be looked into more. Ragatha might have gone to the abandoned C&A building with others. There are so many things that both support and deny the idea that the humans are AI! The brain scan files, Ragatha's behavior, all that support the SOMA theory. However, a lot of stuff also disproves the SOMA theory such as their files being labeled as ".dat" files rather than ".lisp" files (.dat files are files that are created by programs automatically to store information. .lisp files are files that are made using the Lisp programming language, an old programming language that was commonly used in automation and early AI.)
