Most of the desktops I saw people using in 2004 had like 256-512MB of RAM, total. They've got 512MB of just graphics memory. And then on top of that its a GPU from 2010, so this isn't "an early 2000s machine" to assess what performance would have been like. Try running on a SiS graphics adapter on-board with 256MB of RAM, and I imagine their results would have been a bit different.
And then they've got a 480GB SSD? That's an absolute monster of a drive for 2004, practically nothing would have come close to the latency and throughput available on that drive. Even a 32GB SSD in 2004.
I always see people remark "wow look how snappy old computers were" when they're essentially built like $10,000 machines if you were to actually have those specs at that time.
But the question is that, if you were to spend $10,000 or more today will you experience the same snappiness.
I would argue that it's impossible to replicate the low-latency experience of "retro" systems today with the overhead of modern software; no matter how much you are willing to spend.
Neovim is always chasing the shiny new things; while that's exiting it comes with breaking changes, general instability and the possibility of changes that you might not like.
Vim is the exact opposite. You can drop in a .vimrc from 20 years ago it will most likely work fine. It should be noted that this focus on stability does not necessarily constrain innovation (eg. vim9script), it just sets a conservative pace of improvements.

I wonder if there is a term for the subcutaneous fat or whatever that goes away as you age.
It's quiet. No matter how you spin a 100-200K sized city, it will never be this quiet.
