How far back in terms of the level of technological development would you have started strongly opposing or critiquing others engagement with tech (if any), had you been born into the same time period to have witnessed its emergence? And why?

For example many people would have a critique of their friend needlessly building a big fire right next to them on a hot day, making them too hot. But, more specifically, what level of technological development would you have seen as inherently worthy of strong critique and opposition because its use is almost always to the disadvantage of a meaningful life (if any)?
