You are not wasting your time by learning new skills. If for nothing else, it keeps your mind busy and preventing mental atrophy. And it is never bad to have new skills under your belt when you are looking for employment.
Problem here is, age discrimination. Even though they can not ask you how old you are, by looking at your background (I am pretty sure you have a Linked In page which shows a degree with a graduation date or some other social media profile for that matter) or just by talking to you in an interview, they can guess your age give or take few years. And unfortunately, in the IT industry, where younger and more adept to new technologies population is coming out in hoards and outsourcing so much of IT operations to overseas is so easy, there is almost no role for an older worker at an IT shop, unless you are going for a management position. And unless you have prior management experience, no one will ever look at you as a possible manager.
I will be honest. The job outlook is grim for the old timers in IT industry. But one thing is on your side: The Experience and every shop needs at least a few, extremely experienced subject matter experts. My suggestion is to look for those opportunities, by networking with others and finding companies, suffering from conditions that you have the answers for. Those companies more than likely are not aware of their problems. It is your initiative to explain your value to them.
