Or like, the mission of any academic library for that matter? Historically, Google owes its entire existence to an NSF grant that required heavy collaboration with Stanford Libraries, which is why academia to this day holds certain privileges at Google (free GSuite via memorandum of understanding, etc). I'd even argue that working at a library contributes substantially more to indexing the world's information, since libraries usually have one of a kind items in their cataloguing backlog that provide huge insights. As an example, I once met someone at a vintage computing festival who was writing an ENIAC simulator using the original specifications housed at UPenn. Unfortunately, he was having quite a bit of difficulty obtaining example programs to run on his simulator, not because programs didn't exist, but most likely because they were backlogged at UPenn and weren't being added to the library's catalog (i.e., so-called "hidden collections"). There are many ways to work on similar efforts without being at a tech company, but for better or worse the pay isn't remotely as good.
