Haven't we moved into the belief that many/most multicellular organisms are sentient?

Sentience is the ability to experience feelings and sensations. It may not necessarily imply higher cognitive functions such as awareness, reasoning, or complex thought processes. ^https://en.wikipedia.org/wiki/Sentience^

The studies on plant ‘cognition’ and their ‘nervous system’ are not for naught. They have produced doubt. Some researchers are suddenly unsure about the status of plants and this doubt is necessary to get researchers engaged in and to acquire funding for research into plant sentience. The question of plant sentience is one of those fascinating question where, whichever answer is true we will all be in awe. If plants are sentient, then we need to rethink much of our current understanding in neuroscience. How could such a vascular system, different in so many ways from our own nervous system, give rise to consciousness? If plants are not sentient, then we are witness to a self-maintaining entity capable of complex cognitive behaviour without the presence of consciousness. ^https://link.springer.com/article/10.1007/s10539-024-09953-1^

This topic fascinates me. I'm not trying to be confrontational or argumentative, sorry if it comes off that way.
