Welcome to the site, FluffyTwisty!
That Obi-Wan clip you posted is legitimately hilarious. I'm in agony from laughing so hard (I've currently got cracked ribs).

The AI is indeed impressive, this is probably the first time I've heard an AI voice that could pass as a real person. Kind of scary, actually...it's as if Alec Guiness is still alive.
I would like to see Hammond and Anne added as it would provide endless amounts of new dialogue - but at the same time, stuff like that sort of takes away from the magic of actually having Richard Attenborough reading the lines. It's him but also not quite him. AI continues to freak me out.
