These are all entirely reasonable points. I do take some exception with the "now". Has it ever not been the case? Cold fusion. Real AI. Hotels in space. Nuclear powered cars and kitchen equipment. Self-guided cars by the 1990s. Robots as personal valets. Those are part of a long list of unrealistic expectations in the last century.
