"When our time traveler peered into the windows of these shops, the first thing he'd notice was how large all the watches were."
My only question about this entire essay is... where did this time traveler came from???
"Our" time traveler was never mentioned until this line.
It was several paragraphs before that, where pg said "[...] what someone from the golden age would notice if we brought him here in a time machine."
Not true:
> The best way to answer that might be to imagine what someone from the golden age would notice if we brought him here in a time machine. [...] The first thing he'd notice, if he walked through a fancy shopping district, is that all the prominent watchmakers of the golden age seem to be doing better than ever.
