Our notesWritten from the title, channel and description only; the video was not watched, fetched or transcribed. It runs 33 seconds per the feed. The remark attributed to the Director General is reported in the ControlAI description, which puts it in quotation marks; it is not copied here and was not checked against the speech or any MI5 text. The description refers to the update as taking place on the day of posting and gives no other date. ControlAI campaigns for a ban on superintelligence, so the description is advocacy.
