I 100% support it. What I see in global brain is a world of abundance. A world where every single human has all of their basic needs met. The global goal, is to have shelter, food, water, etc. abundance for everyone. As we get closer to the 2020s this will become a necessity in the developed world. Why? Advancing ICT is going to take every single job that does't require education.
Bus drivers? Computers.
Grocery story clerks? Computers.
Your local barista? Computers.
Janitors? Probably computers.
The result? First, as it says in the article, a healthy economy does not necessarily mean everyone has a job. Second, every single person now needs higher education. Higher education is going to become a right in the same way public primary and secondary school became a right throughout the industrial period. And if that's the situation we are heading towards, we need to make sure that no one is worried about rent and food. The thing is, we already live in countries where no one should have to worry about rent and food. This isn't 1950. Our societies are massively productive. We live in abundance. It just isn't allocated properly because the system is fucked and unequal and the board is rigged against all of us who don't have hundreds of millions of dollars.
So yes, there should be a Universal Basic Income (UBI). Will some people do nothing? Yes, that's already the case. Does that matter? No it doesn't. What will most people do? They will get an education and do things that they genuinely enjoy with their life. Could be anything in the arts, sciences, maths, entertainment, athletics, etc. Things humans actually like doing with their life.
For people like me, and a lot of other people in my generation who have educations but are in constant economic instability, this current economy is destroying our early lives and enslaving us with school and credit card debt. If I didn't have to worry about rent or food, I could write far more academic articles, blog posts, invest money in online video, perhaps build a company related to evolutionary science education, etc. There are a ton of things I want to do. Not only does rent prevent me from doing them, but it prevents me from investing in myself.
But it's everyone. How amazing would society be if everyone was able to explore the things that make humans so special in the first place? There are so many bright people who don't try and make something of themselves because of their economic circumstance. Because school costs too much, or because their scared of losing their crappy dead-end job, because there are no jobs at all.
Universal Basic Income is the right step towards a better society.
