I have skills besides technical writing, but it's one of the things I rely on to get hired. So yeah, I'm partially on the chopping block prior to creative writing. And it's a serious problem that all the writing I've done on the internet is being used to train AI.
But the thing about the comparison to humans in morality is there'll be a line that gets crossed. And once that line is crossed, you can't OWN an AI anymore, and you certainly can't sell it. Up until then, you have to treat it as a tool.
The end solution is going to be something along the lines of a Creative Commons license where you specific if your work can be used to train AI, if it can't, or if it can only be used to train non-profit AI.
