The early criticism was overblown, but I think there is a slow, gradual degradation of social values when ubiquitous technology allows people to disengage easily.

I remember being annoyed when a coworker had AirPods on constantly, even when conversing with other people. Obviously we could have a conversation, but it felt like they didn't value it enough to give it their full attention (I don't doubt the music was turned off, though).

In the early days when everyone was starting to get smartphones, there were lots of memes about people staring at their phones constantly and maybe walking into traffic or bumping into people. Constant smartphone use has been normalized now (for better or worse). In the early days, people felt bad when they pulled out their phone to look something up during a conversation, but that behavior is no longer looked down on. It doesn't feel rude if somebody breaks out their phone mid-conversation and starts scrolling for a little bit.
