## Resource

John Johnston (JJ) breaks down how longtime investor Jeremy Grantham asserts that there is a massive stock market bubble, currently being fueled by the excitement around AI, and including Elon Musk’s SpaceX. All-time great investor Warren Buffett also implies the current US stock market is expensive, and that a lot of people are gambling rather than investing.
