Well, I couldn't give an authoritative answer for the whole of science. I'm not a scientist though I enjoy reading about brain studies. What I'm trying to point out is that subjectivity does not mean that there is a self that is observing. The assumption is usually that there simply "must be" something watching. I imagine this is what led Descartes to formulate his famous model of the soul observing existence via the pineal gland. However, we've pulled the brain apart a great deal now and no such interface or similar jiggery pokery has been found. And if I really observe my own internal processing it can be seen that actually there really might not be a self after all.
The sense of their being a subject - I, and, say, a table - that object.
Non-duality = There is a table
Subject-Object voiceover = I see the table.
If we say that consciousness is simple processing, not observation of processing, then subjectivity itself does not disappear. It's just that there is no longer anyone experiencing it. One machine takes snapshots via its perspective and via its circuitry. Another does the same job slightly differently.
