Just some points I wanna make, taking them at face value, pending actual scientific papers:
They have demonstrated the technology working accurately with structures we already know, such as a massive dam, showing the internal structures of the galleys and turbines. So, what they found under the pyramid is at least plausible, and they presented reasonable logic behind how it works.
They didn't make any claims as to what the structure is used for. There were no conspiracy theories about power plants or aliens. The presenter did suggest that the structures could have acted as supports for the pyramid itself to prevent collapsing into the sand or as vibration absorption.
The AI images getting around, I didn't see presented at all. All graphics were either photos, computer data, or generated 3D models based on the data. There was some AI and colourful imagery at the start as part of the introduction, but nothing out of the ordinary from what we typically see these days presented as entertainment. It was at the front of the conference from the people organising it and had nothing to do with the presentation itself.
They seem like they are taking a pretty scientific approach; it's wild to see how people are taking things out of proportion based on random YouTubers putting their own spin on it. Hopefully once it's fully translated and papers come out, people might look at it more objectively. It's such an exciting topic if true.
Link to the conference, skip to 11:40 for the actual start.
