Steins;Gate 0

I think both shows need to be watched if you like AI/SCI-FI related themes. Steins Gate 0 has Amadeus - computer AI with memories of Kurisu while Ghost in the Shell has Makoto Kusanagi who is an android with a human brain but no recollection of the past. Ghost in the Shell has a lot philosophical commentary on what it is to be an android/human and what is the boundary between them.
