Then you need to look at AWS - https://aws.amazon.com/ec2/instance-types/a1/..
Yes, I've been hearing about the Arm architecture moving to servers for about 10 years now. I no longer believe that it will happen, because it seems to always be forecast for "next year". In the last 10 years, all non-x86 server architectures have died one by one, and today even PowerPC is barely hanging on. Instead, we now have a healthy competition between AMD and Intel (with AMD making significant inroads), which is causing their chips to suddenly get much better. If one looks at the roadmaps for server CPUs, there has been a significant acceleration in the last 5-7 years, and it is simply because (a) AMD is trying to make an end-run around Intel, and (b) Intel is actually paying attention to improvements, because for the first time they have competition. This leap forward makes it harder for alternate server architectures (Arm, PowerPC) to make headway.
Well fortunate that you're not in core, then.I don't care at all about respect.
As a final statement, I don't believe anyone here has stated an RPi4 is a server, as in a business class/enterprise rack space server. However, as a home hobbyist server running nextcloud/nas/http/squid etc, it's a great little device.
The issue, you and other anti-RPIn people seem to miss is that a LOT of people are being exposed to Linux through these devices. It's a growing community; it's growing much faster than FreeBSD (IMHO). It's now huge in server space, pushed by the likes of Oracle over even Solaris, loved by IBM etc etc. FreeBSD? Still hanging its hat on Yahoo and Netflix? I know in my work experiences, people want to run Squid, for example, they immediately turn to any number of Linux distributions. I push for FreeBSD and I get blank stares.
Dwindling numbers of fans means you'll eventually become something like OpenVMS: a damn fine OS that no one uses.
