There is a grain of truth I suppose, vis-a-vis humanity's general restlessness, fixing what ain't broke, etc, but I think that this generalisation that anyone who isn't perfectly happy and satisfied with the exact present state of things is "unreasonable" is not true at all.
I guess if the Steve Jobs aquarium urban legend didn't sound unreasonable, you probably have the silicon valley mindset. It's really easy to think of the current state of things and to feel that everything done up to now is 'reasonable'; especially if you live in a really progressive, techno-friendly place like Silicon Valley. You need to know the historical context from the perspective of an average non-technical person in places that aren't as open minded and progressive. One example would be an average person wondering why people wasted their time making unreliable experimental horseless carriages when clearly horses were superior. I also can't help but think of the author of Gulliver's Travels making fun of people experimenting with electricity.
