I agree with some parts, at least. After my recent layoff, I realized I had become too narrow. I knew one language and one subject matter well, and couldn't quickly switch to something else. I was lucky and found an exact fit within a week - but there's no guarantee that will happen again. Definitely doesn't hurt to know a few languages, a few subjects well. Even if you're not an expert, you can fake it for a bit while you get the details down.
