Agree with RogerL here. It really depends on what you want to do and what you are tying to do. But OpenGL isn't going anywhere anytime soon. And at least from what is released so far, it appears, OpenGL and Vulkan will co-exist. There are a ton of things to learn when you start down this path, as RogerL already pointed out, and there are other frameworks and tools you can learn depending on your needs. DirectX, OpenCL, OpenCV, OpenGL all offer good frameworks/API's and do similar things but have specific specialties. Then there are also Game engines that build upon one or more of these that you can start with. If you want to share your goal I am sure you'll get a few opinions and options.
