As for the detriments of tech, that's more on how people grew up with it more than anything really. I'd hardly blame tech imo and given the choice of whether tech should've happened or not, 100% would always say that it should always have happened instead of not at all.
The emergence of AI, the positive side may be as you said with AI work becomes easier and even hard work can be done by AI. The negative side may be with the presence of AI everything becomes instant, finally the human brain that should be sharpened because of a problem ends up being dull because it depends on AI. A small example, in the past when making logos, illustrations, photo manipulation, you had to think hard to find ideas, now the capital is just generate, seek knowledge just generate in chatGPT the results come out without the effort of literacy reading here and there. The point is AI technology is like a knife, depending on how we use it.
