I recently watched a (german) video about the exact development of McDonalds depicted in the meme and it made me realize how much of the experience had been catered towards children and how I felt when I went there more often (or at all) when I was younger.
I actually plan on putting hardware related stuff on an extra pi since I only run a single proxmox node right now. Would be home assistant and nut tools for the ups but I might put pihole and unbound on that as well.
I am worried about the performance though because of home assistant. And it is pretty comfortable to have everything on one host that is far from being used to capacity anyway.
