You're providing valuable feedback about something that probably bothered every viewer of the Hassabis video, so don't apologize!
It's a shame that the best talk (imho) was the one that included the most interaction with the slides. I searched for the slides online but couldn't find them (his publications are at http://www.gatsby.ucl.ac.uk/~demis/ but no slides).
Videos of some of the talks and panel discussions (currently eight twelve of them) from this year's Singularity Summit are now online.
