You couldn't be more wrong. There is mountains of evidence that attention spans have shorted, and parent comment was a perfect example of that. Can't be arsed to deal with whatever you should be doing? Ctrl + pgdown to the twitch tab.
Working in an office pretending that I can focus on the task at hand whenever required by the roster of office life is one of the biggest charades I've ever performed. It's not possible for me and I piss around on the internet on their time when I am unable to focus. I don't feel that's an abnormal situation for people, either, as it seems many of my colleagues also do it.
The major difference is that instead of my mindless scrolling through HN or something at 2pm being on work time that is just lost to unproductivity, it's now not because I can get up and do something (grocery run, make lunch, etc.), and conversely that burst of focus and energy in the evening now goes towards productive work rather than focusing more on a videogame or something.
What is this based on?
But they ought to. ;-)
1. (auxiliary) Be obliged to; have an obligation to; indicates that the subject of the sentence has some obligation to execute the sentence predicate or that the speaker has some strong advice but has no authority to enforce it.
2. (auxiliary) ought to; speaker's opinion, or advice that an action is correct, beneficial, or desirable.
(Even if I've got it wrong, ryanklee claimed that "[i]t's not common" to make that distinction, and pointing to the technical work of philosophers doesn't undermine the claim about common useage.)
