Of Course, A.I. Will Be a Bubble.

A freind asks about this New York Times article about Jim Covello's A.I. bubble predictions.  Do I agree, Of Course.  But so what?  

All bubbles are rooted in an actual advance with financial benefits.  Then that goes too far and there is over-investment, lots of people make money, more people lose money, then the technology continues benefiting people.  Bubble Examples that created overinvestment:  Railroads, Radio, Bowling, Conglomerates, Computers, Home Mortgages, Internet, crypto-currency.  We are currently in a fast moving A.I. bubble and a slow moving index fund bubble. 

More on the index fund bubble later.
