That's what's bothered me about the article, too. "In industry" can mean different thigns, especially if you're going outside of standalone knowledge applications and enter the weird world of the web or enterprise interop. All of a sudden you can't be totally isolated, but you have to talk to other systems. And this is where libraries are actually quite nice. So if they're easier to build in Lisp, great! Then it shouldn't be a problem making them public -- which some Lispers actually do. But don't tell me that everything so utterly trivial in Lisp that every programm has to reimplement it every time.
