How true is this statement: "He asserted that any country with its own language that did not have a sovereign LLM trained in that language was at a disadvantage as a globally trained, English-speaking LLM would not know about that country’s history, news and culture that was described in the local language."

I thought all big players already train on basically everything remotely available to them no matter the language or quality, so his take sounds like an opinion formed in the early days of generally available LLMs.
