I didn't fully grok what this was about from the website. Though just last night I was talking to a friend about that quote from the Matrix that Morpheus tells Neo, so some nice synchronicity there. The sense I got from this is that they are developing a triple AAA type virtual world that can get generated on the fly based on text prompts? When the authors say frame level control do they mean that at any point, the next frame can be manipulated, either to be completely new or to influence the current story or context that is being played out?
