I do believe you have learned plenty outside of interacting with electronic devices. And I am not saying you have to leave your niche either, if you are fulfilled and stimulated that’s great.

But to suggest that you can learn and understand everything within your tiny bubble is really demonstrating a lack of depth and wisdom... At least you should be able to understand and accept that you are choosing to disengage with a vast amount of knowledge that cannot be provided by your current sphere of interest. If you accept that, then that is a good start.

It doesn’t mean your pursuit of knowledge is invalid or useless. But an important piece of growth that sometimes but not always comes with age is beginning to grasp the vastness of what you don’t know, how much is out there that you cannot even begin the comprehend.

The other side of this is a bit physiological. You mentioned in another comment that may skills and concepts learned outdoors have analogues online (like navigating the internet). I just wanted to add that these are very different. Our brains have evolved for millions of years to navigate a physical environment and have unique mechanisms to do that based on vision, smell, even magnetic forces. The inherent attuning of our brains to the physical world is why things like using a mind palace technique for memory are so powerful. There are many other mechanisms like that which can’t always be exercised in a meaningful way via the internet or technology, and which contain their own opportunities for knowledge and growing ones understanding.
