Systemd provides a modern user space which fixes a huge number of problems. At first I found it difficult to learn but it had things I needed and I made the effort. I will always be nostalgic about things before systemd because I started using linux in the mid 90s.
I’m not going to throw away my GPU and multi-core CPU and go back to a 386 running dos because multithreaded applications and speculative execution scare me. There is no way to match what modern systems can do by taking old architectures and just adding more gates or faster clock speeds. And there are parallels in software architecture.
There is absolutely nothing wrong with running a BSD or a non-systemd linux distro if you like. They are still perfectly usable in a lot of situations doing the same stuff people did for years in these systems. If you have a server with a static set of devices that runs a fixed set of services at startup you don’t really need systemd. I still have some systems like that but systemd also handles those cases more efficiently and robustly.
You see these sort of link dumps from people who think vaccines cause autism or that some diet will cure cancer. Whatever the intention behind it I always associate it with a bad faith attempt to fuck with people’s heads by bamboozling them with more information than they can rationally analyze.
Believe what you want but you might want to consider that all the experts working on systemd and using it productively might know their shit.
AMD is by far the best choice for foss drivers. Intel might be an option in the future but I have no experience with their new cards. A second option would be good for Linux users but it’s unlikely to be NVIDIA.
