It's not Erlang it's anything. A screw driver is a pretty multi-functional tool: you can undo screws with it, you can push the cork in a bottle of wine, I guess you could shank someone with it. However, that doesn't mean most of those uses are optimized. I'd much rather read an article that says a screw driver is an awesome way of inserting or removing screws (much better than saw a hammer) than read one saying it's the right solution for every problem. Personally I open wine with a corkscrew, and no, I've never shanked anyone.
