I think it's more about existential crisis than electronics. People don't have focus because they don't have focus in their life. They drift along the trend and only have occasional focus when it is forced upon them (e.g. deadline tomorrow morning). They don't really need focus, IMHO, because most of the things they work on don't require that. Social media and other things just feed them the phantasy that they are "focused" and "have something meaningful to do". I kinda agree a previous commenter that there will always be entertainment (and those entertainment are trained to grab your attention) around and removing some from us won't fix. I also found that lack of energy plays a role. Whenever dealing with a difficult topic (e.g. studying something difficult), my energy level drops fast and in maybe 20-30 minutes it's totally gone and I cannot force my eye balls to fall on the reading material any more. As mentioned in another comment, I believe I also fell victim of "juggling", whenever I'm learning online (i.e. without a book), I tend to multitask if the material is not very challenging (i.e. does not need focus). That brings me the conclusion that modern web learning platforms such as edX and modern course designers tend to simplify/gamify the material by cutting the material into very small chunks (most of the videos are sub-5 minutes). I would like to fall back to the traditional learning experience in which we read physical books, working on real electronic components and have to make appointments to ask questions (or grind in library for hours, even days for one single issue).
