Another Nice Blog Post about Component Software

I just ran across another great blog post about component software, this time from Graham Lee.  This article describes Brad Cox's vision of software ICs, components inspired by physical integrated circuits.  Brad Cox is the creator of Objective-C, a superset of C that implements a Smalltalk-like object system and is the foundation of the application-level APIs of NeXTSTEP, macOS's Cocoa API, and GNUstep.
