Every day you spend learning about PHP is a day that you are not learning about the languages that are really moving the industry forward to interesting new places. That's "chasing shiny". Shiny is the cancer destroying the computer industry from the inside. Any day not learning how to do web application development in LISP is a day wasted. The old tech is still cutting edge, way ahead of any new shiny garbage, because that garbage is decidedly not moving the industry forward, just introducing one more variation of making a computer do something. And that's extremely bad.
