I have thought about this also. Especially when it comes to mobile technology. For most of my career I have been an advocate of mobile technology like smartphones, I have recommended it, I have set it up for people, and now I look at the world and honestly wonder if we wouldn't be a better place without smartphones.
Thing is, we are iron mongers. We build tools. We give people tools. "It is not the tool that determines its work, it is the mind mind of the man who holds the tool that does." (-Brannon LaBoeuf).
Does that absolve me of all responsibility? No not a chance. But it does offer s or a suggested path forward.
The harm that comes from computing for the most part, IMHO, doesn't come from users. It comes from people who exploit the users and users who don't realize they are being exploited. Meta, TikTok, Snap, Google, etc. these are the guys causing the problem.
So as technologists, we have an opportunity to change course. To show those who rely on us ways to use technology without being exploited. Yeah I realized to some degree it's a drop in the ocean, trying to piss up a rope but there are little victories to be had.
In short, be the change.
