What commenters are saying

Commenters compare Incremental to observable patterns, noting advantages in lazy evaluation, weak connections, and automatic dependency tracking that minimize recomputation in large, changing DAGs. Several relate it to systems like Excel's iterative calculation, Clojure's Javelin, JavaScript signals, and build systems like tup and Salsa. One commenter notes Jane Street's ability to package niche research ideas into usable tools. Another shares a link to an opinionated map of the incremental computation landscape.
