"mehr Schein als sein" = "more appearance than substance"

I saw Google's demo of Gemini (tweets linked below) and it looked amazing but overly rehearsed. I get that demos are used to sell a product. OpenAI Dall-E 3 demo was better than reality but it was still within limits. I wonder what I will think of Google Gemini model after getting a chance to use it. 

I will resolve this market after using Gemini for at-least two weeks. I will be kind to Google and will only resolve this market as "Yes" if my experience doesn't match the stuff we saw over the past couple of days at all.
