130T unique pages? That seems highly unlikely as that averages to over 10000 pages for each human being alive. If gp merely wants texts of interest to self as opposed to an accurate snapshot it seems LLMs should be quite capable, one day.
I think a more interesting question is how much information there is on the internet, especially after optimal compression. I'm guessing this is a very difficult question to answer, but also much higher than LLMs currently store.
