Thank you. The up-front complexity is still there and it might take quite a few days to see your first triangle. But I promise, everything will get much easier from that point. :)
The thing I'm most interested in doing when starting a new project is pretty much never to spend a few weeks and writing 10-20k LOC to get a triangle on the screen, I think I'll stick with OpenGL for the time being tbh
You'll need 1k LOC to draw a single triangle and not 10-20k.
Sticking with OpenGL is understandable, but I can recommend learning some Vulkan as a side project (with the help of vkguide) without too much commitment. That's how I started and it turned out to be not as bad as I imagined! Uour mileage may vary, of course.
