Holiness & the 21st century -- particularly "screens".

I was raised in a holiness Pentecostal church associated with the UPCI, and my coming of age coincided with the arrival of computers and the internet. The denomination I was in was extremely strict about worldly entertainment -- we didn't go to movies, we were very careful about the movies we watched on VHS/dvd, and so on. How have efforts to maintain holiness and standards change with the coming of smartphones and the like? I have noticed that my parents, who never had a TV in our home growing up, are now GLUED to their tablets -- often watching shows that have content that would have NEVER been allowed in my time. Some of that owes to bad content becoming more or less normative, but there's also a sense -- on my part -- that the DISTINCTION of holiness Pentecostals being set apart has gotten smaller. I, for instance, I have no tv in my home; I don't watch shows indiscriminately, and I minimize my phone use as much as possible because I don't want to rot my mind. Even if the material I am looking at is perfectly wholesome, I think there's something fundamentally corrosive about smartphones and being always online that corrodes our ability to pull away from the world and focus on things that are serious. But I notice among people from my parents' church that they more or less get sucked into the same habits of constant distraction and consumption that everyone else does.

(For those who might wonder about my own perspective: I had a crisis of faith at age 20, returned to Christ at age 26, and now consider myself a "mere Christian", in CS Lewis' phrasing. While I am not a Pentecostal, I have a ready affection for the faith that gave me my Christian foundation, and occasional fellowship with my parents' church.)
