>>Siri and similar voice-recognition assistants could become the new secretaries. If they improve significantly, look for an always-on version that looks for a keyword trigger and talks back through a speaker. Having an invisible servant would be a serious status marker, but only if it becomes both reliable and ostentatious. Having the quiet space necessary to do this regularly is a marker by itself.

I like your list, but doesn't the low incremental cost of a virtualized assistant, as available to Joe Biden as Joe the Plumber, take this out as a marker?

I suspect most markers going forward are going to have to be physical things that are more rare, and frankly somewhat useless. 6 legged genetically engineered green pocket pigs with stupid haircuts and matching sunglasses kind of thing.
