It's more about those that work from the office mostly, maybe go into meetings etc... and then home occasionally (or right now, mostly).
At work, I'm on a dock... at home, I'm on a 4k-kvm switch... so I'm not really using the laptop but for a lighter computers... Just got bumped to 32gb ram, which is most of the laptop bottleneck. Though my personal system (r9 3950x) is much faster than the laptop (i7 8550u) both on 1tb nvme.
I'm envious of your 3950x, but on the other hand I suspect I'd never actually max it out. I should get into video editing or something to justify more PC upgrades...
Even then... Literally the only time I max it out is when I'm doing a handbrake x265 encode on a faster preset... the slower presets only use about 75% of CPU. If I did it again, would probably go with a 3900X and spend the extra $250 towards an RTX 2070 Super instead of the RX 5700 XT that I got.
My old computer was over 5yo at upgrade, with a mid-cycle upgrade of a couple components, likely this will be the same, though I don't think I will ever go RGB again.
It's the TESmart KVM Switch... HDMI 4K 60hz 4:4:4, I like it okay. Seemed about the best option on Amazon, but mixed reviews. My display is 60hz, and I don't play many games, so it works well enough for my use.
I did get hdmi adapters for my pi4's, but haven't actually tried them yet. May need different adapters/cables if you're going to/from mini-dp or another interface. back of the switch looks like USB-B Female (standard USB cable, not 3) and HDMI Female.
I've only been using it for about 4 weeks, but so far working well.
