You are right that it is the style of how you communicate something that matters as well as understanding your place in history. Perhaps Turing resonated and Engelbart didn’t is because of when they spoke. But there’s another aspect to this and that is perhaps engelbart didn’t understand his audience. By comparison jobs went to the computer club not to seek acceptance but to sell. Once he realized they were not his audience he moved on to an audience that would. But in engelbart’s case he kept selling.
