I thought Project Hail Mary by Andy Weir had a similar "feel", though it's more future-looking rather than past looking.

Daemon and Freedom(tm) by Daniel Suarez is another book (printed as two books, because reasons) that is ~1K pages but I've read 3 times (like Cryptonomicon).

Others in this thread have recommended The Baroque Cycle, but I just couldn't get into it. Ditto with Anathem. Maybe I should give them another try. However, I do love Diamond Age and Snowcrash.
