When people think of AI they think of robots that can think like us. That can solve arbitrary problems, plan for the future, logically reason, etc. In an autonomous fashion.
That's always been true. So the goal posts haven't really moved, instead it's a continuous cycle of hype, understanding, disappointment, and acceptance. Every time a computer exhibits a new capability that's human-like, like recognizing faces, we wonder if this is what the start of AGI looks like, and unfortunately that's not been the case so far.
