I don't see how your point negates my answer to your question. For the vast majority of topics that one would take to ChatGPT, two year old information is fine. You should already know if you need more recent information from another source.

For example, if I want to know how green onions and yellow onions differ in terms of culinary applications and why, nothing that has been discovered in the past two years is going to change that; ChatGPT is fine. But if I want some information on COVID-19, then of course ChatGPT probably won't give the best possible responses. Like any tool, ChatGPT has its uses and knowing its applications and limitations is important.
