A typical answer to any somewhat complicated question: it depends. If you will find use cases for your newly obtained knowledge the you will be able to secure a job. It's all about practicality. You most likely will get hired to solve a specific problem and if you will be able to market yourself and showcase how your skills can boost revenues, you'll be okay.
