We were using an idiom to talk about human relations :)
But one that was particularly relevant considering the historical developments that it referenced.
But no, not everything new is good. There are plenty of new things that fail. You had narrowed in on advancements that increased productivity and had implications for leisure, which I'd say focuses on the new things that work, not the ones that don't.
After all, a failed program--a bad new thing--is likely to harm productivity and intrude into leisure, unlike the ones you seemed to have in mind.
