One possible way of getting at this is to ask if people were more ‘happy’ when there wasn’t this level of tech available - and I’m not sure the answer is yes - I mean, there’s the mythos of ‘a simple life’ and ‘noble savages’, but from what I’ve read of life even a 100 years back - I would surmise folks were as unhappy / miserable then too - but likely for different reasons.
I think expecting just tech to make us happy is framing the wrong problem space.
