There's a few particular problems we have with the word intelligence/sentience, mostly revolving around that we evolved embodiment first and then added more and more complex intelligence/sentience on top of an ever changing DNA structure.
Much like when humans started experimenting with flight we tried to make flapping things like birds, but in the end it turns out spinning blades gives us capabilities above and beyond bodies that flap.
Back to the embodiment problem. For us as humans we have limits like only having one body. It has a great number of sensors but they are still very limited in relation to what reality has to offer, hence we extend our senses with technology. And with that there is no reason machine intelligence embodiment has to look anything like ours. Machine intelligence could have trillions of sensors spread across the planet as an example.
