I've thought like this for a while, even before AI. I figure that if I do write, it will either be ripped off, outdone by a person, or suspected of having been ripped off from somewhere. There are also topics I would not feel comfortable blogging about because they are not PC. I think it is worth developing the skill of writing however. I haven't found a real way to solve these issues 100%, but it occurred to me that the odds of me having these problems would be lower if I paywalled my stuff or at least required registration for access. Free registration would not work if everyone did it the same way, but perhaps there is a way to have your own system that no crawler would bother trying to interface with.
