Assuming the only purpose of universities is to serve the job market. I'd argue that the primary function of the university system is to transfer the collective human knowledge forward. The fact that some of it is sometimes needed in jobs is a secondary effect.
But you're right that there should be schools that teach the practical programming skills. But it's the the trade schools that should be developed towards this goal, not universities.
Anecdotally, I was (as probably many here were) ahead of the curve in digital devices usage when I started hanging out in IRC and various web forums as a teenager in early 2000s. At some point I noticed that just using computers induced some amount of anxiety compared to "old tech"; whenever there was some period of time when I used my computer less (like christmas, vacations, etc.) and joined back to the "world of the normal people", I felt much calmer and happier. Even though I noticed this, it was difficult to log off during normal times since most of my life was in the internet.
Now everyone is using digital devices all the time and the "normal people world" has ceased to exist. Also almost everyone is anxious and/or depressed. I think this is not a coincidence. However, I do not think that this is due to social media per se, but using digital devices for anything (social media being just the reason why most people use them).
My theory is that just using digital devices for anything is somewhat stressful; you have to keep the eyes focused all the time (Can you think of other activities that require this? There aren't many and they are all somewhat stressful), you have to navigate all the various applications and menus, you have to occasionally solve minor problems that you run into when using the devices, etc.
Using digital devices is the same for your brain as heavy, repetitive physical labour is to your body; in small amounts it might even be healthy, but several hours every day is going to destroy your body/mind.
Really? Here in Finland I see a lot of products in the supermarket that claim to be made out of "100% recycled plastic". I can't really compare volumes of plastic waste vs recycled plastic products, but it seems that at least some of the recycled material is put to use.
