Assuming PayPal etc lasts 30 years do you think they will have at some
point rewritten their entire codebase in the flavor of the day or will
UseNet in 2054 be talking about the ugly, obsolete patched up mess?

The problem with trying to rewrite old software, and I’ve done it, is that
the only “specification” is the code itself. You either write a lot of code
that may have been in the old program but never used, or miss a line of
code that doesn’t seem to do anything that causes the whole thing to blow
up if it’s not there. There’s no way you can test enough to guarantee that
the new system is 100% compatible with the old one. I would never recommend
rewriting a working system.
