My brother was a math major at Texas Tech. He dropped out in his senior year because he said the math stuff they were teaching him was ethereal and had no connection to reality.
From there, his bona fides got him a six year stint in the US Navy as a radarman. He finished his enlistment and went to General Dynamics, then to Lockheed then to GE Astrospace and retired as a project director.
He went back to Texas Tech and without taking any courses, was awarded his BS degree based on what he had accomplished.
He’s still a doofus to me, though. LOL

If Tsoukalos' Aliens were to gift century's of math advances, it would not be as damaging as bequeathing finished technology---humans would still have to interpret, then apply an understanding of the math.
This helps mitigate a human cultural collapse prompted by an encounter with a much more technically advanced culture.
