We have discussed this repatedly. Apparently it's news to you that not every vitalist must believe everything that any vitalist has ever believed. That's not my problem.
I am unsure what your concern is. Is it that life might be required at some point to begin consciousness?
C-T offers no account of the origin or pre-history of the systems in question. If it turned out that there were some requirement that only living systems could build non-living conscious systems, then C-T would (I think) be unaffected. What mattered to Church and Turing was the functional specification, not how a particular satisfaction of the specification was achieved and maintained.
Personally, I wouldn't worry too much about whether antecedent life was necessary for non-living consciousness until I had resolved the actual C-T problem and had a non-living consciousness to wonder about.
The video in the OP, like many good thread-starters, proposes a lot of things. Even if it were undisputed that some of its claims were ridiculous, there would remain the unridiculous questions of what did happen, why do some people interpret it one way, while others interpret it differently, what is the religious significance of this ... lots of good questions, IMO.
So, I think that's an interesting search. And I think it will take a while to sort out. That being the case, who's qualified to participate in the search? Who's disqualified?
Might a physicist be able and allowed to contribute some insight to the questions before us? A philosopher? A mathematician? An engineer? Who's on your black list? Anybody who hasn't studied biology recently has been proposed. What's yours?
I note also, what with this being a religious board, the supposedly limited-debating religious board, that some religions which feature an incorporeal afterlife claim that what exists apart from a brain is a dramatically altered human consciousness. Adherents of those religions would likely disagree with the vid's apparent favored interpretation of the events, as would those whose religions offer an exclusively corporeal (resurrected, for example) conscious afterlife. I think that's an interesting aspect of the problem.
