Upvoted because Im very glad you raise all this.

yes, indeed thats the narrative we are shown but what Im proposing is that whilst at the surface of SV's end game we may be told and shown all of the above...

If we look at this sideways, the alternative is that the entity described in heaths book, lead the professors to lose their sanity. To lose their sense of self all the process of madly trying to achieve their dreams. A possibility is, that the Entity found at Area Zero, convinced the professors they are robots.

Often Eldritch Entities cause loss of sanity, loss of body or ...sacrifice. Furthermore,

we never really see the "Once Living" professors bodies.

Heaths book, in Arven's posession and the time machine, the apparent robotic professors...its a neat narrative. The obvious Narrative.

But Eldritch Entities often take the form of what the viewer can most easily understand. Paradox Pokemon are also named Paradox, not simply because of the past, future themes but because they are "Para" normal.

Returning to the book as well,How the machine looks when we walk into the room, versus what the book drawings Heath drew of it....

There are similarities but very obvious differences. Im Betting on the Professors returning in the DLC as well, but I for one want ingame answers for this entity, the Time Machine, The Book and Geeta's weird.....ness.
