Ask HN: Why do LLMs call Trump "former president" despite current knowledge?

THIS POST IS NOT POLITICAL.

I noticed that when I ask Gemini, ChatGPT, Perplexity and other LLMs about current events, they would sometimes refer to Trump as "former president".

The reason I find this question-worthy is that this happens despite the fact that the LLMs have otherwise "realtime" knowledge about the events in question.

As an example, they'd say something like this: "Trump ordered the attack on Iran. The former president said...".

Does this observation offer an insight into how LLMs process information?
