The features described seem of dubious general value, but don’t seem like things that would work without an LLM, especially the smart text area. (Smart ComboBox sounds like it might be more generally useful than the others.)

But the point of these seems to be more of a solution looking for a problem than attempt to find an efficient solution to an identified problem. Or, rather, they are one of Microsoft’s many efforts as part of looking for a solution to their problem of “how to do we monetize our investment into AI technology” not a solution to customer problems.
