Has anyone

found any meaningful text in number expansions of pi or e?
in base 36/26/whatever.

Since pi/e is transcendental it contains all sequences of possible data.
Every file in your computer, every post on 4chan, every book, every video and things that never been written or created before. The question is "Where in the pi/e the data sequence occurs?".
If you could find it before the universe ends, you get infinite compression(location in pi/e + number of bytes to extract). You could also find all information that could possibly exist but not known yet or hidden/secret/lost/etc.
