Without the internet, I'd probably be in the same work; while the 'net has been an incredible tool for networking in my field, all of my most profound inspiration and interactions have been more analog - save the television. Without the television, I might be really lost. Thank God for the television.
If the internet were to go away forever tomorrow, I'd probably continue doing the same as I'm doing now, although I'd be rather lost in many ways. I can imagine that I'd want to share and circulate some of my ideas, which is yet another signpost that it's about time to start a blog...I'd probably try to do more work to talk to people about the practical purpose of physical training as a method of liberating the self, and how I at least think that the liberation of the body is the gateway to the liberation of the mind and soul.
When I think about who I am and what matters to me, and how the television was so important in understanding that, it causes me to consider how much the internet matters and how it could be so much more. While I've been rather doom-y reading Surveillance Capitalism, the prompt of this post is net inspirational :)
Major edit: If the internet never existed, my life would be nothing like what it is. It's only because of the internet that I met the most important person in my life, and it's possible none of it would be the way it is. Yes, my work would very well be as I described. But my life? No.
