The capabilities of individuals over 70 are hugely varied. Some folks are clear-minded until 100, others start to lose their mental faculties much, much earlier.
I don't think the generation is forgotten, just so vastly different in needs from the core audience that it would require an entirely different solution, and likely an entirely different company model.
Back with Windows 3.11, it came with a paper thick manual telling you how to use the OS. You could read it, and understand it, and you only had to learn how to use the mouse (the difference between right-click and left-click, and how to double-click fast enough), and also knew that scrollbars looked like scrollbars at all times, buttons behaved a certain way at all times, and UI elements were visible and behaved the same at all times.
I think we've lost that with modern UIs and it's a shame.
One other thing a lot of older people learn is that if they don't want to deal with something they can feign helplessness and someone else will jump in and do it for them.
Different neighbors, being on different circuits, being on a line that's more likely to have storm damages, can make a lot of difference in quality of power delivery.
I've lived in places where the power practically never went out, never experienced undervolt situations, etc. I've then lived less than a mile away from the same place and experienced seemingly monthly issues of all the clocks being reset at random times when I come home. Living closer to things like hospitals, fire stations, emergency operations centers, etc. seem to give the best indication of power reliability, at least from my personal experiences.
But then VideoGuide [1] was released (available from RadioShack). I begged my parents for that and honestly it was the most amazing product and worked flawlessly. I felt like I was living in the future.

The last couple of VCRs we owned even had automatic time setting. It read extra data in the vertical blanking interval from our local PBS station.
I was surprised that kind of thing wasn't much more common earlier - it wasn't really any new tech breakthroughs so much as someone just going to the effort of building it.
who is right - no way to know, everyone can make their own judgement.
I've seen the same scenario - someone with limited vision, next to no feeling in his fingertips and an inability to build a mental model of the menu system on the TV (or actually the digi-box, since this was immediately after the digital TV switchover).
Losing the simplicity of channel-up / down buttons was quite simply the end of his unsupervised access to television.
The thing that didn't scale was the new (weird, not sure why) latency in tuning in a channel after the DTV transition, and invasive OS smart features after that. Before these, you could check what was on 50 channels within 10 seconds; basically as fast as you could tap the + or - button and recognize whether something was worth watching; changing channels was mainly bound by the speed of human cognition. I think young people must be astounded when they watch movies or old TV shows where people flip through the channels at that speed habitually.
Because with analog signals the tuner just had to tune to the correct frequency and at the next vertical blank sync pulse on the video signal the display could begin drawing the picture.
With digital, the tuner has to tune to the correct frequency, then the digital decoder has to sync with the transport stream (fairly quick as TS packets are fairly small) then it has to start watching for a key frame (because without a keyframe the decoded images would appear to be static) and depending upon the compression settings from the transmitter, keyframes might only be transmitted every few seconds, so there's a multi-second wait for the next keyframe to arrive, then the display can start drawing the pictures.
I'm pretty sure there's a lot of round-tripping going on with the streaming services I use through my dongle. They're always slow to both start the app and to start any actual streaming.
I found it amusing the other year when a youngster knew what the save button was, and recognised it, but didn't know what it was - a floppy disk (as he'd never seen one).
