Thought the same - the trailer came across as dull. Especially after having seen Alejandro Jodorowsky explain in this documentary what he envisioned with it the trailer seems like yet another self-indulgent Hollywood movie.
your blog post assumes that the participants all engage in the communication with collegiality and those questions are just an unfortunate misunderstanding.
guess what - if somebody asks "are you there?" it's often deliberate power play with the intention to get from you a verbal commitment to be fully available as soon as you answer affirmative.
philosophically I like the idea of a UBI. but realistically I don't believe anymore in solutions based on financial reorganizations. the society needs a fundamental shift of how resources are allocated and used. I expect a UBI to only produce a low-income class that depends on UBI and can't find a job that pays sufficiently well and another high-income class that just gets the UBI on top of their ample salary. prices will factor in the new offset and adapt positively. we'll see more low paying jobs for UBI-dependent people who can't choose.
