Yeah, to me the fact that you can write stuff like "Hello, my name is Jerry and I'm 28 years old. I'd like to create a project. Could you do it for me Timmy?" is only useful to attract new users. Like you say in your conclusion, once they lose their fear of having to "learn commands", they become more comfortable and eventually they will try to use the product in the most efficient way possible (e.g. by using shortcuts).
