Your comment seemed dismissive of the possibility of a problem, and of the possibility of that problem being exacerbated by screentime/phone use/tablet use. Ergo my interjection.
As an analogy, that I think is apposite, some people can smoke tobacco and not get addicted, for others it becomes a consuming need; I think electronic interactions can be like this for many people. I get tetchy (irritable) when I don't have a drink for a few days, a similar tetchiness takes me when I don't get my fix of phone time. Screens can provide a very easy way to avoid social interaction, something which is a challenge for me. Stick this all together and you have problems connecting with people that are exacerbated by increased screentime; I do have the agency to avoid getting completely absorbed by devices but I also exercise that agency on behalf of my kids as I believe they have not (as pre-teens) developed the ability for themselves.
It seems to me, you did make that claim.
