Very true, my comment was just frustration venting, not criticism, so I hope you didn't take it that way. There is absolutely value in just telling people the future can be good. Star Trek also does this, and either predicted or is in some cases arguably responsible for a wide variety of things that either genuinely do or can make the world a better place already, but this video makes the case that simply showing a hopeful vision of future might be the most important thing it actually does.
