Esilarante.

Era consapevole che la transizione dell’Europa è letteralmente condannata senza la Cina? Forse. O forse credeva sinceramente che l’UE potesse costruire da zero le proprie catene di approvvigionamento per la transizione. Un continente che non riesce neppure ad estrarre le proprie risorse di shale oil dovrebbe iniziarea ad aprire miniere di terre rare. Probabilmente sarebbe più semplice iniziare un allevamento di unicorni.

 
Annie: I have the intuition that is probably bad. What are the adverse effects of that lowered attention span that means switching screens, moving back and forth between tasks?
Gloria Mark: There are three types of adverse effects. First, we know that errors increase. There has been a long line of laboratory studies that show that performance worsens when you switch back and forth between tasks as compared to doing tasks sequentially.
Second, it takes longer for people to do things. Let's say you have two tasks and you're switching your attention between them. It takes longer to do either task than if you were to finish one in sequence and then move on to something else. The reason it takes longer is that every time we turn to a new task, we have to reorient to that task. We have a mental model, and we have to summon up that mental model again and apply it to this new task.

Annie: This is all bad news: We have 25% of the attention span that we had two decades ago. It is making us make a lot more errors. It's slowing us down because there are switching costs. It's adversely affecting our health, increasing stress levels. It’s changing our brains. But then we hear people all the time say things like, “I happen to be very good at multitasking.” Are we ever truly multitasking? And if so, is it actually realistic that all those people think they are great at it are great at it?
Gloria Mark: The answer is complicated. Yes, we can be good at multitasking, but only as long as one of those activities uses automatic attention. I can drive and have a conversation with a passenger because driving is generally automatic, but as soon as a car tries to swerve in front of me, I stop talking.
If two or more tasks involve controlled processing, we are not really multitasking in the sense of doing things in parallel, at the same time. We're switching our attention back and forth. When people switch their screens, they are using controlled processing because they're looking at what's on that screen. Maybe, to some extent, if you're surfing online, you might tend to do that automatically. But if you're reading any content on that page, then it is a kind of controlled processing.
