Why Elon Musk doesn't invest in controlled nuclear fusion

Sure, Elon Musk's a con artist -- but, aren't most scientists and engineers con artists, much of the time, anyway? Let's consider the case of controlled nuclear fusion research. Elon Musk says "What do we need controlled nuclear fusion research for, anyway? We've got a perfectly good nuclear fusion reactor up in the sky. It's called the sun! Let's just build solar panels to use that already existing controlled nuclear fusion reactor, why bother trying to build our own?" Now, as usual with Elon, with have to differentiate what he says, from what he really means by this. Bear in mind, Elon has some training in Physics. He has a Physics degree from the University of Pennsylvania, and very briefly did graduate work at prestigious Stanford University in Physics. How briefly? He spent two days in graduate school. Now, what could 24 year old Elon have seen in just two days to convince him to get the hell out of there. I can tell you quite exactly. He saw that every single damn science professor was a Lord unto himself in his own laboratory, and that no matter how ridiculous what they were doing was, any graduate student had to profess absolute fidelity to their Lord and Master, and absolute faith in their ideas and research. So, Elon knows very well that researchers are just making it up as they go along, and have to lie their heads off to survive in their system. And, you see, there's a very basic problem with all controlled nuclear fusion research. You see, as far as we can determine, there's only one place nuclear fusion occurs naturally in the entire twenty billion year history of the universe -- in the interior of stars. And, this requires enormous pressures -- thousands or tens of thousands of times earth's atmospheric pressure -- and extremely high temperatures, on the order of tens of millions or hundreds of millions of degrees. So, in a sense, we've really had "controlled nuclear fusion" for seventy years now -- H-bombs, that is. These approximate the conditions in the interior of stars, and achieve comparable energy potential. But, this isn't quite an optimal arrangement. Too much energy, too much radiation, too dangerous. What we want is a "no tears" approach to nuclear fusion. We want limitless energy in a form that can be safely used in our baby's bath water. And, nuclear fusion researchers, being professional researchers trained to lie like rugs, are perfectly willing to promise just that. Now, actually, there isn't the slightest reason to think controlled nuclear fusion researchers can do what they're so enthusiastically promising to do. None whatsoever. It doesn't make any sense at all, and is completely inconsistent with anything we've ever designed or experienced. And, Elon Musk is trained and experienced enough to see this fact. But, what of the scientific method, you ask? Surely, the "scientific method" guarantees progress, systematically, to achieve any technical goal? I'm afraid, this isn't true. All the scientific method is, is trial and error, somewhat refined by public criticism from other scientists, since the advent of printed books in the sixteenth and seventeenth centuries. The scientific method doesn't guarantee progress from point A to point B. In general, scientists can't be sure of anything much more than being able to get from A to one millimeter from A. So, Elon Musk is shrewd enough to avoid this particular lemon.
