It seems that the global economy is like two extremes of ice and fire.

On one side, the AI industry is experiencing frantic investment, factories working overtime.
On the other side, there is unemployment, a sluggish market, and while AI is very popular, it's out of reach.
Countries unrelated to the AI industry are even worse off.
The momentum of this market rally is entirely driven by investments from American giants.
It's a bit like China's 4 trillion yuan infrastructure push in 2008.
However, China's invested money mostly circulated internally, boosting employment, and infrastructure has long-term effects domestically.
This round of American investment, in the end, mostly flowed to East Asia.
If this investment ends up being a failure, and AI cannot turn a profit, the U.S. could face serious problems.
