People were "put together" during the era of evolutionary adaptation, during which almost all emotional attachments were created between humans interacting in real life. Nowadays, we have all sorts of ingenious ways to *feel* like we are experiencing someone else at an emotional level without them being physically present, and this is in part responsible for our collective cultural obsession with a few exceptionally beautiful and/or talented people.
I don't see how feeling an emotional attachment to an actor, a writer, or a goldfish translates to "*feel* like we are experiencing someone else at an emotional level". We feel an attachment. It's there, it's real within us. Done.
You appear to suggest that those who lament Williams' death think that Williams cared for them. I do not think this is the case. I'm pretty confident Pratchett is unaware of my existence, yet I can still empathise.
To return to my earlier question, you're sure you do not experience this yourself with anyone or anything that does not reciprocate?
