I got a blindsight vibe when interacting with early ChatGPT through rot13 but I can’t be sure if it was real uncanny valley (pseudo) consciousness or me anthropomorphizing. Probably the latter. It really shows how much work was put into making LLMs not scare people.
Conversing with early GPT-4 (in the first days of Bing chat) was surreal beyond any non-drug experience I know of. The infamous negative behaviors are well documented [0] but every part was so... alien.
