Whether it be the out-of-control federal government, the stock market bubble, the AI bubble, or the IPO bubble; no matter where you look, you see the irrational and unsustainable. The pin that pops it can't be known ahead of time, or anticipated with precise accuracy. The best that can be said is that when it's time for the pin to be there, it'll be there. Often, it's in hindsight when we can say "That was it. That broke the biggest bubble of them all." Educate yourself on sound principles before this happens. There will be a high demand for those principles.
