Gary Marcus has been saying this since at least 2012:

To me it feels like having continually predicted rain throughout the longest dry-spell in history. Eventually you'll be right (assuming that we'll move to some other paradigm in due course), but it's hardly prophetic.
I think that the challenges of intelligence and non-shallow reasoning will inherently involve fighting against diminishing returns (which is what the supposedly broken scaling laws predict) regardless of technique. Same as for computer graphics - doubling the compute doesn't double the perceptual quality, but that doesn't necessarily mean it's hitting a wall.
