The internet is already useful in the way you are imagining it to be. The educational and practical resources are there, and are not that hard to find assuming you have gained minimal technological literacy and a certain understanding of internet culture and critical thinking relating to the content available.
There is a ocean of addictive distractions to wade through, but at the same time we know the following things:
- We have to be constantly mindful of the Gell-Mann amnesia effect
- News sources and journalism have always had significant quality problems when they venture beyond just reporting basic news, even in the case of business-oriented publications that as Chomsky has pointed out have a vested interest in delivering quality reporting
- Understand topics requires delving into the academic literature in many cases. In this scenario, the internet becomes the line towards that literature or those long-form articles but most of the users' time has to be spent reading and thinking instead of just browsing
- Identifying skinner boxes and addiction traps is easy. You usually know when you are in one. We have to just be honest about what our goals in life are and how much progress we are making towards them
What this does not solve is the problem of focusing on the wrong things in life or embarking in a career or interests that are ultimately deleterious to your life. But the internet at least makes it far easier to pivot and refocus as long as you let it do so and use it towards a conscious goal. This mindfulness is easier said than done but it's far from an impossibility.
