I'm moving to France in September and reading posts on this site has already helped me a lot! Thanks for putting it up. I'll be sure to post my own review once I've settled in!
This is super inspiring and really makes me want to try a similar experiment. I've been wondering how I can make income while doing month long stays in different countries throughout the world, and this seems like it would be about perfect. New country, new project, enough income just to get by. Keeping the price low is not necessarily a mistake. It will allow you to pick from a much large range of products and if you can live for two months on $2000, why not just keep it low. The world doesn't necessarily always have to be profit-maximizing.
P.S. I checked out your essay about the first person view. I think you should watch this video from the BBC. It describes how this first person view that you describe is not actually making the decisions for your body, an MRI machine can predict what decision you will 6-7 seconds before you become conscious of making a particular decision. This doesn't necessarily answer your question, but the video shifts the question from why am I making decisions to why does brain make me think I'm making decisions.
Does this seem exploitative to other people? Although it is exciting that his app launched, the fact that this entrepreneur is being called "The Homeless Coder" seems wrong to me.
