Technology is not a good-only or evil-only thing. You have use cases that are beneficial and you have use cases that is not benefical. The technology in by itself isn't what makes things worse. Even many thousand years ago, humans used weapons to bash in other humans. Remember the Ötzi: https://en.wikipedia.org/wiki/%C3%96tzi#Body he was killed by arrows, most logically from someone else shooting at him (at around 3230 BC). Nuclear energy is used as weapon or source for generation of energy (or rather, transformation of energy). And so on and so forth.

IMO the biggest question has less to do about technology, but distribution of wealth and possibilities. I think oligarchs need to be impossible; right now they are causing a ton of problems. Technology also creates problems, I agree on that, but I would not subscribe to a "technology makes everything worse". That does not seem to be a realistic assessment.
