Society has accumulated enormous "societal debt" (think technical debt). Most things are inherently broken and inefficient. They haven't changed in centuries.
- Communication
- Education
- Emotions
- Jobs
- Housing
- Clothing
- Health
- Nutrition
- Politics
- Economy
We can't fix these things incrementally. The social codebase is worthless. We need to start over, from scratch.
Buy an issland or a big piece of land. Carefully select people based on a yet-to-determine algorithm (people with as little exposition to society, such as kids), and send them there. Closely observe what they do, and ensure they don't repeat and/or bring with them habits and ideas that we know to be wrong. This will take a while, but at some point we will be able measure how they perform as opposed to the rest of the world. These metrics could include happiness (although difficult to measure), ratio of time they spend doing things they agree with (willing to do, not coerced), energy consumed, etc.
Most jobs are utterly useless. Most people have no idea what the fuck is going on. People don't have a purpose or focus. We really have no clue. Logical fallacies make up MOST of our understanding of reality. We live in constant fear and anxiety, and dedicate a lot of resources to cope with it. We quickly become convinced that money is an end rather than a means. We miss the big picture, we lack empathy, we avoid introspection. We believe in lies, myths, bro-science. We don't have a clue about what habits or foods are healthy for us. Regulations and the monstrosity of the legal system make the simplest thing unachievable by mere mortals. We have technology that's thousands of time more efficient than what we had in the past, yet our lives have barely changed (i.e., the hours of work).
Like it or not, most of your active time is spent at work. We work 20-100 hours a week just to get by. Surely, getting rid of 80% of jobs (at least in countries like the US) while maintaining people's quality of life would a real breakthrough. Yet, I would argue that this is already possible, without the need of any additional technological breakthrough (i.e., AI). Look around, most jobs only fulfill habits and historically relevant needs that we can easily get rid today.
