Maybe it's the paper? I have a Lamy with a fine nib and it's amazing. I mostly use decent printer paper, but coarse paper like a typical composition book is not so great.
Same. I'll be driving along or walking down the street and my mind will wander to "I wonder what Franklin would think about cars. How do I even explain how they work? And let's not even get into cellphones." Faraday is another common target. It's always someone I could picture having a beer with, rather than some interminable boor (I imagine) like Newton.
The "tour" description is perfect; I'm always explaining or showing the person around or something. I imagine there's some ego component here; I only have a popular-science level understanding of these things, and my explanations would only be interesting to someone from the past or otherwise detached from society (which is also something I think about).
This all manifests as a bit of a mind game or thought experiment; it's not as though I'm actually conversing with the person. It's almost entirely one-sided: me imagining how I might explain the world to someone smart and curious but without any modern scientific knowledge.
I had that Apple powerbook G3 that had two hot swap bays for batteries/hard drives/media players AND a PCMCIA slot. Oh, and built-in ethernet. I remember adding Firewire support via PCMCIA. Good times.
I use Apple products at work, and am otherwise not very invested in the world of Apple. I frequently will have to look up how to accomplish a task or get a particular piece of software working, and the author will assume that I'm familiar with where macOS <some place name> fits in the chronology vs. macOS <some other place name>, requiring me to look it up.
Worse for me than the Android dessert names were, since at least those were ordered.
