What's the first evidence of people saying "I think the future might be like this", as we get in the 1920s-30s etc., giving predictions for what e.g. new technologies might mean for civilisation?

I'm not thinking about Nostradamus and soothsaying/seer-like predictions for specific events, but instead suggestions of predictions for changes in society, perhaps driven by technological developments, perhaps driven by societal progression.

This perhaps assumes that the civilisation doing this thinking does not assume it's the peak of humankind's civilisation. (Please note I'm not asking an alternate history question, but instead asking what is actually documented about contemporary views of the future)

If this only started happening fairly recently (e.g. in the 1920s-30s, or perhaps Victorian times), did people write in any meaningful way about whether things would be different 2, 3, or 5 generations after their time, or was the expectation for much of history that the only things that would change would be who was ruling, rather than societal shifts within that?
