What if it's not harm, but adaption? Why would our brains survive hundreds of millions of years through evolution by adapting to everything around them, only to then then get broken (or "harmed") by the devices that those same brains proactively have designed, created, and then actively _chose_ to use en masse and now can't live without them? Could it be that the decrease in attention and memory is a reasonable adaption? If there are way more things to pay attention to, because we're all now much more aware of everything that's going on around us, it kind of warrants having shorter attention span by default, with moments of intense focus in rare circumstances. Same for memory, part of the reason why we invented computers is to be able to store and retrieve information better than us, and we succeeded. Now our brains are delegating to those external systems and focusing on things that truly require our intelligence. I know this is controversial, but I think there's something to it. I think that what is happening right now is justifiable evolutionary pressure on human species.
