I think the article makes a good point, but perhaps I'm over-interpreting. It's not that we should stop using strings. It's that we should use the type system to separate different kinds of strings and enlist the compiler's help to detect incorrect mingling of them. So for example a symbol type would only permit strings that contain ASCII letters, underscore and digits, and concatenation with / conversion to plain strings would be limited.
