Actually, I wanted to say something very similar. And when you said it was for his very specific _96_ year old grandma, I went back and checked if I missed the obvious. But a quick 2nd scan (and a search on the string 96) didn't bring it up. I'm not saying you're wrong, indeed I'm pretty sure you're right, but it's very-very far from obvious. Also, the initial tweet itself talks about the issue in pretty generic terms: "a machine that helps our beloved elders to keep communicating with their grandchildren ." My parents are around 80, and granted my father was an engineer and my mother a programmer they did have exposure to computers from their 40's and 50's. (Actually, my mother started around the age of 30, but my father only when he was 50.) Sure, another 15-20 years make a lot of difference. However, plugging cables is more 1900's technology (reminds me of the manual switchboards). I doubt too many people alive today remember having to make a call like that as opposed to dialling. They did use radios that had push buttons and most of them for sure used ones with digital tuning. So while it looks very retro, a simple turning knob would have been a lot more sane. (Unless grandma used to be a switchboard operator :) and still has good hand coordination.) The other thing I don't get is the thermal printer. I mean it's nice as a (very short term) archival device but an LCD screen (or even and e-ink display) would make a lot more sense. Of course, then you have to add scrolling (that could be a tuning wheel-like thing or just up/down buttons). Or well, maybe they would like to hear their grandchildren :). But I digress: the point is that it was phrased pretty generally and I also think it's very patronizing. (My parents use skype, viber, email, fb chat as they did use SMS and their mobiles.) While sure, there is value in completely tailoring it to the needs of specific person. Just don't think it's in general a good approach.
