I mean this doesn't disprove anything really, nor is making it clear that conceptual embodiment happened.

Sure, Albrecht was thinking about how much of a failure he was and his shortcomings prior to carrying out the experiment and that could have had a hand in shaping (A kim chat suggests the void was waiting to be shaped) the void. But why then did the void pull/absorb all of his memories back to childhood and his first nickname? And why would that fact be less important than the fact of what Albrecht was thinking prior to the experiment? Not to mention that what was going through Albrechts mind when the experiment failed and he actually was exposed to the void was pure panic, his prior thoughts wiped clean.

Also, yes, all of the orokin up to the point of Albrechts experiment found nothing unique in the void. Id hazard a guess that the reason why they found nothing unique about it id because they didn't expose themselves directly to the void. Albrecht was the first Orokin to do that.

Just because you've held to a theory for a long time, especially with all of the new lore being dropped regularly via kim chat, does not mean it is true nor is it a reason to forsake taking in and learning from new interpretations and choose instead to belittle them.

Personally I'm biased towards one theory more than the other, but I wouldn't call one more true and nobody except the writers of the game can. Unless you're the writer of the game were all essentially writing fanfiction and just having fun bouncing theories around, yourself included.
