Air conditioning, satellites, and CAT scans are just too far beyond imagination that I don't think it would be fully appreciated.
Maybe 80% of US Americans now have access to a larger variety of fresh fruits than even most nobles had 200 years ago, and it's not even a big deal to us.
Project that kind of progress another 200 years in the future... it's hard to imagine how that would even look like.
Tea, earl grey, hot.
I don't think folks, at least not the well-off, would have a hard time understanding any of the varied payment methods we use today, since they'd been doing conceptually similar stuff[0] for centuries by the mid-eighteenth century.
Come to the US and drink all the raw milk you like. Note that we don't have universal health care here, so bring lots of cash.
I think there are two aspects to this. I think anyone who's ever been to a food market in the history of time would conceptually understand it's possible to have a bigger market, and perhaps even a faster horse or mechanical bird to bring the items there. Commerce bringing you items from the other side of the world is millennia old. So I think it would be more of a case of "how did u mad lads actually pull this off", rather than a true mind-blown situation.
True mind-blown'ness I think comes from other examples he brings up, like GPS, and making items apparently hover a hundred miles above the earth and transmit information from above there, instantly, silently and invisibly. That's supernatural stuff, and the realm of the holy or the uncanny. You can't go back very far in time without talking about that stuff getting you accused of heresy / talking to the devil.
