My personal experience with C# and Typescript has been that explicit typing like that rarely provides much value. Explicit typing tells me one thing and one thing only: GetOwner() returns a Person. But when I have questions, they almost always fall into the realm of "details about the GetOwner() method" or "details about the Person type". I honestly am struggling to think of any examples when seeing a variables type answered all of my questions. Honestly though, this is a tooling problem. There's no reason at all that developers should need to spend time encoding information into the source code that's already known to the compiler, but devs also need to use tools that can feed the compiler's knowledge back to them. Jetbrains Rider (and their Resharper extension for Visual Studio) have a set of options called inlay hints [1] that do this exact thing. Personally I tend to keep most of the type hints turned off because they do add a lot of clutter, but the feature is absolutely invaluable for parameter name hints.
