My view is that consciousness, the seat of "personalness," is the ultimate reality, and is also scientifically impenetrable. In other words, there is no scientific test one can postulate that would definitively prove its existence in another entity. We assume that other biological human persons, at least those who are at least acting conscious, are indeed conscious. But this too is an assumption, and this shared human consensus breaks down when we go beyond human experience (e.g., the debate on animal consciousness, and by extension animal rights).

Ray KurzweilWithin a few decades, machine intelligence will surpass human intelligence, leading to The Singularity -- technological change so rapid and profound it represents a rupture in the fabric of human history. The implications include the merger of biological and nonbiological intelligence, immortal software-based humans, and ultra-high levels of intelligence that expand outward in the universe at the speed of light.
