The "AI Winter" was largely caused by people realizing building better logic, chess, or similar analytical engines proves to be a poor model for human like intelligence. The current renaissance is due to Machine Learning / Deep Learning based essentially on statistical models.
In the specific context of language there was a famous debate between Chompsky and Norvig that touches on these themes: http://norvig.com/chomsky.html
I believe events of recent years have not been kind to Chompsky's side of this debate. I'm less bullish on large language models turning into AGI than many people here, but I think if we do develop AGI it's a certainty it will be a based on probabilistic models, not logically consistent formalisms alone.
I think this is the right link. It's the initial story from the point of view of the person whose work was plagiarized. The evidence of plagiarism provided there eventually led to the story that I submitted.
