Is there any saying that exists about overestimating stuff in the near term and long term but underestimating stuff in the midterm? Ie flying car dreams in the 50s etc.

Gates seems more calm and collected having gone through the trauma of almost losing his empire.
Musk is a loose cannon having never suffered the consequences of his actions (ie. early Gates and Jobs) and so he sometimes gets things right but will eventually crash and burn having not had the fortune of failing and maturing early on in his career(he is now past the midpoint of his career with not enough buffer to recover).
They are both dangerous in their own ways.
We still don't have flying cars 70 years later, and they don't look any more imminent than they did then. I think the lesson there is more "not every dream eventually gets made a reality".
