The problem with futurists is that they're greedy. They want the future now instead of when the technology and systems have been built out to make it a reality. UBI falls under this umbrella. UBI is a poor attempt to cobble together a future paradigm into our existing system. It's not going to happen, it doesn't work. You should be building towards you grandchildren's grandchildren's future when post scarcity is closer to reality and then they won't even need UBI.
