Sounds very cool and inspiring, but we’re talking about rich people.
Rich people historically have been able to just stay rich whatever happens. Sometimes a little less rich, sometimes much richer. A few notable exceptions, but then again… raising kids to aim for “epoch changing discoveries” is just a silly overblown expectation.
If you have money it's easier to make many more meaningful bets. You don't need to aim for epoch changing discoveries, just use money to become a benefactor of them.
