yeah this is knee-jerk anti-technology shite from people here because we live in a society organized along lines where creation of AI would lead to our oppression instead of our liberation. of course making a computer be sentient is possible, to believe otherwise is to engage in magical (chauvinistic?) thinking about what constitutes consciousness.
When I watched blade runner 2049 I thought the human police captain character telling the Officer K (replicant) character she was different from him because she had a soul a bit weird, since sci-fi settings are pretty secular. Turns out this was prophetic and people are more than willing to get all spiritual if it helps them invent reasons to differentiate themselves from the Other.
