This is starting to remind me of the switch from ASM -> C or more recently, the switch from pure HTML/Javascript to frameworks. Technology advances and if you don't follow the advancements, you will suddenly find yourself laid off with no job prospects. This happened to my cousin last year. He's in his early 50s and was the subject matter expert on decades old technology, which nobody really uses anymore. He was laid off and when he tried to get another software development job, many interviewers laughed at him for his outdated tools and techniques he used. He ended up getting a job as a mechanic and will most likely not get back into IT.
