I take your points, but find it just a little sad.
I guess it boils down to whether or not you believe that texting via the Internet is somehow better or more desirable or more fun than actually communicating directly with someone.
Maybe it's a generational thing. Hmmm....would I rather talk to someone in the flesh or on the phone, or should I just text him/her? Damn...my thumbs are getting sore, guess I'll have to resort to the old technology and make a call :-)
NB: not every vessel afloat has a computer. Or a text screen. Or connection to the Internet. Or, thank god, wants to.
But almost all have a VHF. And, long-distance cruisers have a SSB which they can switch on in the morning and listen to while they're making breakfast, fixing a piece of broken gear, herding the kids, looking over new charts, or eating some papaya with lime juice. Try that while you're glued to the keyboard :-)
