The Titanic sinking kills five more

“Man fired for criticising homosexuality”, or maybe “man imprisoned for refusing to hire black person”.

People are thinking about technology, but in 1923 people were very familiar with breathtaking technological change. The complete reversal of some social norms, on the other hand, would be almost existentially disturbing to these dudes who believe in the great benevolent Christian empires, and in some cases thought ending slavery was a mistake.

I have to wonder what the residents of the 1920’s third world would think. I’m sure there would be many interesting perspectives.

Probably all the climate change shit

Also if you told a guy from 1923 that the world’s most industrialized nation was China they’d probably accuse you of lying

Most international experts consider the outbreak of a third world war unlikely in spite of global surges of violence

Not mundane, but the implications would be horrifying to 1923 society still recovering from “The Great War”.

Climate change, same sex marriage (though, perhaps not as shocking as some might expect, ditto anything trans related), potential mars colonization, coming off the heels of the Spanish flu, COVID news would probably freak em out. Ooh, the USSR being gone, and China being a world super power. The USSR would have been new to them, and it collapsing less than a century later would probably feel quite odd, especially if you could make them understand just how incredibly advanced the USSR got in such a short amount of time. Tons of stuff.
