I have no interest in the minutia of people's lives as seen on Twitter or Instagram.
No argument there.
IME, text messaging takes more time than analogous conversations.
If what you need is a conversation, then yes, certainly. Overall, the written word is just about the lowest bandwidth communication form we have available to us. Face-to-face or voice-to-voice is certainly better for fullness of communication.
There are occasions when it is a better option
Specifically, when there is a very short message or exchange, and it is okay (or actually preferrable) for it to be asynchronous. The overhead of a "conversation" of repeated back-and-forth voice messages is greater than that of text messages. If your life doesn't lead to these, then yeah, text messages aren't something you need much.
but for the most part, I find it inefficient and annoying as fuuu......nk.
Well, funk has its place - Motown. Not so good in cheese or feet
I also have ethical and legal concerns about the way ISPs handle email, but that's a necessary evil, and my concerns will be addressed when certain cases are played out in court...
I acknowledge that this leads into politics, but I admit to being curious about which cases you mean.
