Technology

Probably. If their primary trait is being a visionary, having creative ideas about how the future could turn out is gonna produce the occasional hit.

The problem is usually that they're so far removed from the lives of normal people that they genuinely can't imagine our perspective anymore: They don't know what day-to-day challenges we face, how our financial worries influence our priorities, how much purchasing power we have, how that influences our price-to-payoff estimates... They also tend to be quite unconcerned with technical limitations and assume there's gotta be a way to implement whatever they cooked up.

3D TV is a great example: In theory is a fancy luxury for people for whom "regular" 2D TV isn't quite enough. In practice, the technology wasn't (yet?) ready to deliver on that, particularly in the face of the various difficulties (having to wear glasses, struggling with eye strain, health issues and so on).

The idea that consumers wouldn't jump at the chance to replace their TVs with a new, expensive and quite clearly immature technology probably didn't intuitively register with people for whom $1k is a negligible sum.

Probably CEOs in the 70’s and 80’s that predicted that computers would become ubiquitous and part of everyday life when computers were still only used by scientists, business people and hobbyists. Like Steve Jobs.
