The data is out there if we give at least wheels to a robot and let it bump into things like we did when we were little. We didn't need a billion pictures or videos. Only trial and error, then we developed a mental map of our home and our close neighborhood and discovered that the rest of the world obeys the same rules. Training AIs doesn't work like that now.
I think that they want to follow the same route of LLMs: no understanding of the real world, but finding a brute force approach that's good enough in the most useful scenarios. Same as airplanes: they can't fly in a bird like way and they can't do bird things (land on a branch) but they are crazily useful to go to the other side of the world in a day. They need a lot of brute force to do that.
And yes, maybe an AI winter is what is needed to have the time to stop and have some new ideas.
