However that is not quite what happend.
Attendees starting asking questions not related to the VTT session they were in. From Alphastream's blog:
"When lunch was followed by another VTT discussion, the questions began to shift. One after another, the attendee questions were about equity, accessibility, creator support, localization, hiring and promoting marginalized staff, trust, and problematic content."
Wizards tried to direct things back to the agenda. When that didn't worked. They hastily added another session which became the AMA session. My point is that session was never planned, and the attendees were asking questions unrelated to what was presented initially. So it is no surprise the presenter of the VTT wasn't prepared to discuss them. Regarding the AMA, Alpha said this:
"This pivot was not easy. I know when I have arranged professional events, I put a lot of energy into preparation and I can be slow to pivot (something I am trying to improve). To their credit Wizards provided the extra time and worked through very difficult moments. Staff jumped in, covering blind spots – which speaks to how important it was that Wizards had dedicated so many staff to being present."
