I would say I'm more a slave to my laptop than my phone but its because its my means of generating an income, then naturally used it for other things like entertainment. I think like anything we humans get a hold of, we create unhealthy obsessions at first as we see how far we can push the limits of any tool we are given, you can see that all throughout history until today, eventually we find our equilibrium and move on to something new
I think its not the tool that's the issue but what we use it for, if you're using it to generate an income great, if you're using it to be unproductive, not so much. I think the real issue is being productive, we have so many distractions now that keep us from being productive, and that's where we as humans find meaning and why we feel so empty in this modern world
