Jeff,
you have summoned me here today because I understand you have a question for me about the economy.
Yes, it's the million dollar question right now.
What do you got?
Are we in a bubble?
That's like a several trillion dollar question, I think.
Look at the stock market right now.
The S&P 500 is up almost 50% over the last two years.
Yes, it is absolutely bonkers.
Bonkers!
And what is even more wild is that
if you look at what companies are mostly responsible for that growth,
it's just a handful of them.
It's the companies doing AI stuff.
Yes, all this AI stuff like Microsoft and Amazon and Meta.
People are calling them the Magnificent Seven.
Yes, and we would be remiss if we did not mention NVIDIA.
NVIDIA, of course, is the microchip company that's powering all this stuff,
and its stock price, I think it has almost quadrupled over the past two years.
