|There's more than one way to do things|
I have never heard of TIOBE before, and I won't choose to pay any attention to it starting now.
Journalists love “the next big thing.” Even if they don't understand what is, they do know that “the next big thing, whatever it is” will probably help sell issues and maybe even subscriptions. If you confront someone with something they don't know too much about (an easy thing to do ... with everyone), and then you proclaim that “if you don't learn about this, then It Is The End Of Your World As You Know It.”
Hogwash, sure. But it does sell issues and subscriptions.
Become good at what you do. Always work to become better. But also become good at letting other people know why what you do is important to them. I'm not really “talking technical” here, because the business value of what you do really isn't that closely tied to how you do it.
In other words, “you could provide good business value in COBOL. Or (ugh...) PHP. Plenty of folks are (still) out there doing just that. They can describe what their well-running software does for the company without mentioning any language-names at all.
