There is a pattern that repeats every time a transformative technology arrives: first excitement, then a flood of capital, then the hype.

Finally comes the reckoning: where it becomes clear that the technology succeeding is not the same as an individual company succeeding.

We saw it with railways. With electricity. With the internet. And we are seeing the similar hype phase with AI in 2026.

• How Grigsby-Grunow dominated the market and went bankrupt in 4 years.
• The two questions every leader should be asking to find their "Philco Moment".
