Yes and no. It all depends in what field you're describing sound. In physics, a tree that fell in the forest most definitely made a sound. In psychology, it doesn't.
In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid.
In human physiology and psychology, sound is the reception of such waves and their perception by the brain.

To be honest, I'm with the physicists.
Nah, as long as you keep following recommended security practices it can be useful to get rid of unneeded load being put on your server by malicious bots.
I had a lot of problems with botnets hammering my SSH service on my private VPS. Moving it to a different port would only work for a few days before they'd be back at it again.
I wasn't worried they'd get in. But logging in to my server would take ages because it was under so much load (VPS is pretty low-spec). Finally decided to shove my SSH service behind port knocking. Got rid of all the bots knocking at my door.
Obscurity has its uses, as long as you don't consider it a replacement for security. It's just an additional tool.
That's a phishing attempt. Had a few of those in the past. At least in my case they attempted to make it a bit more convincing by adding an old password of mine that got leaked online.
I'm currently on Pop! OS 22.04 LTS. For me it worked out of the box. That installer with the NVidia drivers already included was a dream, so I didn't have to set up anything special. I did end up preferring the KDE desktop over Gnome, so I just went screw it and installed KDE plasma on top of it. It's been my daily driver like this for years.
Though, honesty requires me to mention that over the 4-ish years I've been using it they pushed a kernel update twice which killed the nvidia drivers, causing you to be unable to boot to the desktop. Solution was as simple as just rebooting into the previous kernel for a while and waiting for an update which fixes it, but still...
Other than that, pretty happy with it and I'm unlikely to change anytime soon.
