If you think that "25 years of not blowing up" is a sure-fire way to predict the risk of blowing up in year 26, I would recommend reading Nassim Nicholas Taleb.
I never said "sure-fire" or anything like it. Anyone who believes in "sure-fire" investments is a fool. The theory that people with lots of money to hire the best are fools doesn't seem credible to me.
Besides, Warren Buffet has a stellar track record much longer than 25 years. People paying him to manage their money has made him very, very rich and those people very happy with him.
