Ivroy tower implies to me that someone is an academic who's deep focus on theory makes them myopic to the practical aspects of a subject. It still implies credibility, albeit sometimes not directly appliapplicable to problem solving. John unfortunately has no academic basis for any of his predictions at all. So yeah, I agree very much with the second part of your statement. His entire worldview is formulated from sci-fi, often of questionable taste, that he barely even understands. Its like watching a little kid except that instead of being inspired by a childs naive yet hopeful dreams of the future, you are just grossed out by a mentaly ill, 40 year old guy, ineffectively cosplaying as a woman, who you would think would know a bit more about his field.
