>By implied I meant "caused". I did not meant "made people speculate that it might do something theoretically"

That's on you. Implied doesn't mean "caused".

>Also, what sci-fi authors and futurologists write is utterly irrelevant here. We should distinguish fantasy and reality

A useless distinction, since what sci-fi authors were saying was taken to be a foretelling of things to come, adopted as such by many voices in the wider cultural space.

And of course futurologists were people who made (or attempted to make) informed predictions and even policy suggestions of things to come, not mere "fantasy" peddlers.

>Practically, technological progress does not implies working less, it implies higher productivity

That's your concept of it. Hasn't been historically the concept people (from technologists and journalists to politicians and sociologists) had of it. And even if it matches how things went, it's hardly the only way things could have gone (or should go).
