Are plants sentient? What about asanna-satta, and AI?

Why are asañña satta considered to be living beings? It seems like (from very brief description) to be even less sentient than plants. They both have rūpa, and I believe plants to also have jīvita indriya

About Asañña beings, there is already a topic about this theme.

Is there any mind in the unconscious being of 4th Jhāna brahma realm?

Just curious, as I haven’t got the chance to properly ask this before. Now that this is a resource for commentaries, subcommentaries and abhidhamma, I want to ask if there’s any mind left of the 4 aggregates of mind for the unconscious beings in the 4th Jhāna brahma realm. There’s not much info about this in sutta. How do they differ compared to a person in cessation of perception and feeling absorption? Why don’t they get insight into Nibbāna if the two are roughly the same?
