I agree with you however I do think there's something to be said about the actual actions behind it.

Addicted to texting was certainly a thing, I remember others certainly having it growing up and I myself remember the anticipation. But, it literally is just talking to your friends. At the very least the nature of conversation, to me personally, takes away some of the negative connotations. Being connected to a friend as a form of escapism of the real world, often with kinship as your friend felt very similar to how you did.

Compared to the usage today where it's not conversational. The endless scrolling through posts, to the point where people like and I didn't make enough content for the feed so other random content starts getting added. If the social media does have communication interactions, it's likely not someone you know from real life and the depth of the interactions aren't as deep. When texting all day you either run out of things to say and become complacent with the menial texting or you engage and delve deeper. Some early socials were able to mitigate this by still being able to have personality through it - obviously MySpace, but others like Gaia Online as well were apt for having an online presence. Now everyone and everything is so bland and exactly the same.

It was a tactical move by social media, widening the scope of meaningful interactions out into the friends list on the internet. Why stay talking to one to three people all day when you can be talking at 150+ people every day!

Anyway I hope this makes sense lol. I definitely agree that both were addicting but I do think texting at least is rooted in a social bonding and then reinforced with friendship at school, unlike the contemporary options where the friends likely aren't even in the same state (which isn't inherently bad by any means, but having that tactile friendship makes a huge difference)
