By the logic that today's news is fundamental to know as true, there really is no point in reading books older than 6 months old. If Einstein woke up from a coma, he'd be useless, as he doesn't even know who won the World Cup. For real now, if an AI can help you solve a problem using 2,000 years of human logic, does it really matter if it's "skewed" away from a political shift that happened three weeks ago?

I also don't believe that everybody I know is idiosyncratic in the way they view the world. And even if they were, I'd probably just pay attention to the things that are directly relevant to me. So probably I'll misunderstand most of what they say anyway.

The post doesn't question the value of historic knowledge.

The idea is that a base model could be years old, with all it's faults; superficially fixed and extended with knowledge over time. She points to a research that LLMs don't "fully believe" this new knowledge. The skew could be much longer then a few weeks.
