alt Hacker NewsAll I can say for certain is that 10 years from now there will great OpenGL-to-VulcanMetalWhatever translators, at least as good as the ones already built-in to several graphics stacks today, and the learnopengl.com tutorial and examples will still work. So unless you actually intend to compete with AAA game engine designers, you may safely invest your time in OpenGL.
The anti OpenGL sentiment is so strange to me. OpenGL is basically supported everywhere even in places where Vulkan is unpopular.
Any sane person who actually wants to do low level graphics programming should rather work on the libgodot effort since it will make it much easier to use Godot as a wrapper around Metal and Vulkan by defining a custom RenderingServer without even touching the Godot scene graph or having Godot own your application lifecycle.
