Why are AI.Engineer talks/transcripts/presentations not available for attendes?

An attendee at the AI Engineer conference in San Francisco, where tickets cost roughly $1,500, reports that transcripts and recordings of talks are not available even to attendees. Staff at the desk mentioned something about a YouTube release and engagement but said they did not know why the material was not released at least to attendees, and offered to forward the concern up the chain. The author, who has ADHD and memory encoding issues, says they wanted the recordings to convert what they learned into lasting facts before it fades within 48–96 hours.
