A paper presents mold, a Unix/Linux linker that parallelizes the entire linking pipeline, linking multi-gigabyte debug binaries in seconds and outperforming lld and GNU ld.
For engineers building large C++ programs, link times are a known bottleneck. mold's reported speedups could significantly shorten the edit-compile-debug cycle. However, it is a Unix/Linux linker, so it won't help on other platforms.
