There were definitely people "at the top" who were essentially arguing that more scale would get you to AGI - Ilya Sutskever of OpenAI comes to mind (e.g. "next-token prediction is enough for AGI").

There were definitely many other prominent researchers who vehemently disagreed, e.g. Yann LeCun. But it's very hard for a layperson (or, for that matter, another expert) to determine who is or would be "right" in this situation - most of these people have strong personalities to put it mildly, and they often have vested interests in pushing their preferred approach and view of how AI does/should work.
