(This is a belated response to Buildings that Blog posted by Warren Ellis last month.)

Now that we’ve had mandatory universal polysensory geotagging for a couple of decades, we can identify everyone who has ever stood on this particular spot, see what they saw, hear what they heard (smell what they smelled, but who needs that).

This has, of course, led to an efflorescence of new kinks, including locaphilia (I find five Ellis posts on the subject to date: here here here here and here), where the fetishist develops an obsessive sexual interest in everyone right here.
