In fact this tradition of rich people founding universities and research is nothing new. Stanford University was founded by a couple who said "The children of California shall be our children" after their child died. Andrew Carnegie founded the Carnegie Technical Schools, and John Harvard donated money and his library to a college founded two years earlier.

While not research, those things can have profound impacts on people. Several years ago a Star Wars exhibit came to the Indiana State Museum here in Indianapolis, they had an entire section dedicated to both the prosthetic devices in the film and in real life, one of the video segments playing next to some props from the film and real prosthetic devices was a clip of one of the inventors of the real technology talking about how watching the film version directly led to him pursuing his career and working directly on various prosthetic devices trying to make it a reality.
These sorts of experiences could have profound impact on the creative process for one or more individuals that might have far more profound effects for society than active research.
If I were a billionaire, that's exclusively where I'd be putting my money, selfishly.
Billionaires buy cars and boats because they're stores of value. For instance, a Mclaren from the 90s is worth more today than when it was sold.
This shows that in the 12 months to the end of June the value of classic cars as a whole was up by 28%, which compared with a rise of 12% for the FTSE-100 index of leading shares and a 23% slump in the price of gold.
