It is a popular conceit to assume that anyone cares about your thoughts or that they carry some significant, intrinsic value. This happens to me all the time. It takes reflection to realize that most of the crap that people generate is just that, crap. Sure, it may be crap that can incriminate you in a court proceeding or crap that could be developed into patented intellectual property, but it is crap none-the-less. Its that tendency people have to assume things like "I got super stoned in the late 90's and sketched out designs for Photovoltaic Solar Roofing systems, that Musk guy stole my idea". No, odds are that Musk guy didn't steal shit from you. Your diary wasn't hacked, your sketches were not secretly photographed and your phone isn't bugged. Your idea was in some way obvious. In the PV example it was obvious and requires money and influence to develop, two things that if you had them you wouldn't be making claims that "so and so stole this idea" or "I invented that first".
