I really enjoy when the voice actors do different voices for different characters. I've always wondered how they do the recording for that.
Do they read all of the dialogue for one character in a big chunk, then move on to the dialogue of the next character? Or do they read through the book naturally and switch voices? I would think that the latter would be very difficult.
I didn't think it was overly fancy or confusing at all. I'm not even a particularly techie person and I found the presentation and material to be very palatable. I came away from the video wanting to learn some more about graph databases which I'd say was probably your goal. Very nice job with this!
I've tried to explain this same point to people but haven't been able to articulate it well. I think you just hit the nail on the head with your explanation.
