I have no idea how much effort Google spent preparing these demos, but I personally find it so much less impressive than the livestream OpenAI did where they actually used their tech following suggestions from discord.
I think OpenAI is probably held to different standards than Google. ChatGPT hallucinates incorrect information, and it's kind of adorable - the tech is early, they'll improve over time, etc. Google Bard hallucinates incorrect information, and it _looks_ like a step backwards in their core product.
