It's good because if you don't know data structures, algorithms and how OS manages memory, files, IO and so on... you are just a web developer who knows how to use your tool.

You can't discuss with people over performance, or why memcached has better performance than redis in some special cases and know why by your knowledge, not some random article you've read explaining why on the web, you can't build the tools you use if you had to. You can't explain much of the ruby, PHP or any language you use's internals. You may grasp what is a garbage collector but can't really reason about it.

Plain horrible, if you ask me. I think it's worth it if you love it.

Otherwise just focus on getting a project manager job or some sort of job you don't need it.
