I feel like every library, every framework, every programing language, compiler, database, VM, debugger, logger, tracer, metrics monitor, editor, source control, artifact manager, build tool, dependency manager, deployment automation, etc. are examples of developer tools that are not collecting dust. My guess is that the tools which try to provide program synthesis just don't have good ROI, too costly to build and maintain in a working state and too hit and miss from the user, and that's why they've been collecting dust.
