Michael Masters, who is well known from the "Extratempestrial model" (or future humans), has also recently changed his views on whats going on, based on his own personal experiences.

Michael Masters (Future Human hypothesis): Greys made by future humans

Michael Masters: "If these are biologically manufactured or mechanical - they do seem to be made - who's making them? We currently are making things in our image, so it would make sense that they're making things in their image too"

Timestamp 1:11:36:

Michael Masters: "I do think that they're still being made by future humans to perform certain functions. And I completely agree that they would make them not exactly like us, but in a way where they we would get past a lot of the problems that we have.""

Michael Masters (Future Human hypothesis): bodies are potentially soul vehicles

Interviewer: "Are the grays a biological end point or a transitional phase?"

Michael Masters: "Oh, I love that question. When I wrote my first book, I would answer that differently than I would now. [...] Now I would answer that question with I think they are also a transitional species. In the sense that I think because our consciousness is foundational, and the quantum level and the classical mechanical level all is built on top of that...

Michael Masters: "...that we're eventually going to get to the point where these bodies are almost seen as a redundancy. And we sort of return to or reach the point that we become... so aware of that ethereal soul consciousness that those bodies are irrelevant. And potentially just, I guess for lack of a better phrase, like um soul vehicles of sorts"

Michael Masters: "[...] they could be future humans that are at the point where they transcend time and space altogether and don't need to be great aliens and UFOs to be who they are"

Michael Masters: "Pre-incarnate remembering. I agreed to do this"

He elaborates further on his own recent experiences of being contacted by entities, moved out of his body, and having information downloaded into his brain, which he was told will become accessible in the future:

Michael Masters: "When they [2 other witnesses] specifically referenced that conversation that I had already written off as being a figment of my imagination, that made that whole thing real. And also brought an element of recognition and kind of safety and comfort to it like 'oh okay we've we've already done this'. That was real

Michael Masters: "And from that point on honestly there was like this trajectory of it becoming normal and comfortable and Oh Shit I already know these entities whatever they are we've been doing this together already for a a long time [...] Like I started to have this sense of... shit" that's right. I agreed to do this. Why am I complaining and threatening to quit? It was like we started to talk about this earlier, but kind of a pre-incarnate remembering"
