I agree with parts of the article. In its isolated way, it's correct. However, a side effect of faster lenses is a shallower depth of field. Thus, for portrait work, an 85mm f/1.8 Nikkor is preferable to, let's say, an f/4 which would naturally have a greater depth of field. So, "faster" glass does have an application, but with modern digital cameras, it's not a needed as in the past.
