He didn't say anything wrong.
All people here making assumption about Samsung's 200MP don't really seem to know what they are talking about.
First it needs to be establish that the S23U DOESN'T take 200MP PICTURES BY DEFAULT. By default it takes 12MP images, so no different than any smartphone of the market.
In terms of details the S23U improved a lot vs the S22U, while if you would follow the logic from people here ranting on Samsung's 200MP camera the S23U should actually perform worse than it's predecessor which is obviously not the case.
Second, Samsung is a company with a long history in photography and a lot of experience and technologies related to this field. They not long ago made very good dedicated cameras. The 200MP was developed by Samsung and even if, even I was skeptical I first, Samsung obviously knew why were doing when they chose to create this sensor.
The 200MP sensor is not a "low end camera sensor" with just high mega-pixel count like a lot of users here are trying to suggest, its a state of the art new camera sensor which performs as well as you would expect a high-end smartphone camera sensor to perform.
Third, regarding pixel binning. The S23U combines 16 pixels into one and there are already comparisons between the default 12MP mode and the 200MP mode. The default 12MP mode massively improves dynamic range and low light performance(so also cleans the image really good when it comes to noise) while the 200MP is incredibly detailed in decent light conditions and it's a huge step up from the 108MP used in previous Samsung flagships.
All in all, in the camera department the S23U is definitely not a disappointment and brings solid improvement from Samsung.
