This is of course assuming that Internet Archive will still exist in 100 years.
The Library of Congress has existed for ~225 years, for example.
I’m hopeful for a future where you can potentially carry all recorded knowledge on a device and media you can fit in something somewhat human portable [1]. But until then, humans interested will maintain and continually improve archival and information retrieval systems to preserve and make accessible knowledge.
