This is how i work it out;
1) "Consciousness" defined as attribute-less pure awareness/witness and immutable "Self" (aka Purusha in Samkhya) will never be possible in AI/AGI.
2) All other human mental states which are mutable and considered as evolutes of Prakriti in Samkhya are possible in AI/AGI. A simple mapping would be;
2.1) Buddhi in Samkhya ~ Metacognition - https://en.wikipedia.org/wiki/Metacognition
2.2) Manas in Samkhya ~ Phenomenology - https://en.wikipedia.org/wiki/Phenomenology_(psychology)
2.3) Ahamkara in Samkhya ~ Emergent property from above due to "I Think therefore I am".
Now realize that (1) is purely experiential/internal and only (2) is observable from an external pov and you get the idea why AI/AGI may seem "Conscious" (in the common usage of the word) to external observers.
