Anyway, as was pointed out elsewhere, someone can write a web CRUD in Rails in 1% of the time it would take to write it in C with Apache modules (or ISAPI DLLs). Choosing the wrong tool can have disproportionate effects.
Having a large tool set is one of the hallmarks of the great programmer.
One example off the top of my head: a friend of mine was struggling for a week to deliver a simple J2ME (it was 2002 or 2003) app using Eclipse. I directed him towards NetBeans. The product was ready that same afternoon. The IDE support in NetBeans was so complete his job was more a fill-in-the-blanks than anything else.
The original article seems to base this on the flawed assumption talent and choice of tools are not related.
edit: should have phrased the above as "this statement seems based". It's not the entire article.
