These are a different in quality more so than a different in kind. In 1922 you could already talk to someone 100s of miles away via the telephone. In 1822 you couldn't. And getting there was going to take weeks. So you basically couldn't talk to people long distance unless you were rich or important.

Means rather than an end here. Google Maps is neat and convenient, but again, you _could_ use paper maps for much of what people use google maps for. And large paper mapping schemes (e.g. ordnance survey maps in countries of the british empire) were carried out in the 19th century and WW1. Communications could also be done, albeit more expensively. Space missions are still currently in the scientific curiosity stage, rather than impacting people's lives, but who knows maybe commercial near earth space missions end up being the one people get to to talk about for 2022-2122.

These are technically more accomplished achievements for sure, but I'm not sure they have the same sort of societal impacts as initiatives against cholera and tubercolosis of the late 19th century. Vaccination is probably the 20th century achievement to call out here.
