Yep, NVIDIA were behind it, as they saw a chance to gain capital, prestige, investment, power, etc. Tale old as time shit.
Fixes can be applied to microkernels just as much as the mainline kernel, the difference is that not as many people would be needed to maintain a microkernel. The scale is smaller and manageable, bugs, critical issues are easier to see and diagnose. Complexity scales down in that case, the Mainline Kernel is massive and complex, makes it harder to work with which is why there are so few large kernels out there as it takes a lot of manpower to maintain them.
Yeah, I feel like you should when you are ready to do HTML and get your website online!
I like to read documentation too, I also sometimes understand it after giving it a few reads. Looking up unfamiliar words. I am used to implementing fixes in my distros by now (previously Windows as well, where it was harder because the Windows Registry is fucking shit). Arch is basically easy mode at this point. I encounter very few things that I cannot fix easily. But my installed software and dependencies isn't that complicated so...It is easy to manage.
While Metal and Dubstep are seen as violent (the lyrics can sometimes be) I don't feel they are inherently. They are just charged forms of expression, passionate, which gives them an edge that most forms of music don't have. I listen to almost all forms of music outside of most rap and country. I like Orville Peck for Country, and a select few rap artists, but not many.
