> Everything around you grew in complexity to adapt to your needs Unix provides rather limited primitives for composition, and a lot of things remain unsafe or very difficult to do right in shell. That's why we keep extending tools and doing things (rather redundantly) in a real (if outdated and limited..) programming language. A lot of that complexity is due to poor design, not due to inherent complexity in the user's needs.
