It's something pretty unique to ML research. The goal posts keep moving whenever an advancement is made. Every time ML achieves something that was considered impossible X years ago, people look at it and say, actually, that's nothing special, the real challenge is <new goalpost>.

I'm pretty sure even as we cross into AGI, people will react the same way. And only then will some stop and realize that we just wrote off our own intelligence as nothing special, a parlour trick.
