@gpuccio The question about the semantic argument was mine, and thank you for responding. Since I’m not one of the main participants my comment got moved, then moved again, finally landing in this new thread.
I did not see any assumptions requiring semantic information (SI), but some of your claims suggest unstated assumptions, and SI would fit in that gap.
However, I still think your definition of FI is inadequate to your purpose. I see nothing that excludes non-biological sources. AND, given the extensive disagreement over examples, I’m not the only one thinking this. The appearance is that non-biological FI has been defined out of existence without adequate justification.
