The "senior trying to use a computer" image is interesting in that it seems to imply that the seniors of the future will be just as clueless about how to use the Internet as the ones today, which may unfortunately not be far from the truth.
I predict that eventually browsers will become almost unconfigurable, highly locked-down, and be less controllable by the user than a television. As the article notes, "the URL will [...] that many users will never even realize is clickable." From there, it's not hard to imagine at some point the decision to remove even that "clickableness", on the basis that "no one will bother to", and by that point the frog has been thoroughly cooked. Open-source or not, almost no one will have the will or knowledge (except the few elite) to modify them to make them work as they desire. Users can be more easily "herded" and persuaded, if they have little knowledge of how things work; just keep them consuming and complacent, because knowledge is power, and we don't want them to have too much of that. Appease and mollify them with eye candy and doublespeak. Welcome to the future of corporate control, mindless consumption, and fashionable ignorance.
Sorry for the negativity, but this trend I find really unsettling.
