Of course you need a CPU capable of multi threading, which today means any CPU, but then there is no doubt that the multithreaded init process is way faster.
This was thoroughly tested when systemd demonstrated it.
Single threaded init processes have bottlenecks, and a single issue will stall the whole process. Of course systemd only influence boot speed of user space, but the Linux kernel itself is also multithreaded in it's boot processes today, because it is without a doubt faster.

I'd use it if it's as good as systemd.

Since it's "open source", we could start experimenting with our own circuitry, implementing the new Booleand logic: ANDD, ORD, XORD, NOTD and all that good stuff. See if we can tinker together a few instruction setsd.

Your file system is mounted under /etcd/systemdd/systemd and you have to acces files with lsd /etcd/systemdd/systemd/homed-userd-Documentsd-myfiled.txtd.file

Yeah, I'm definitely gonna need lsd for this.
