Railroads CAPEX ran 6% of US GDP ... wave after wave of bond defaults. Telecom, just $1T... also everyone went bankrupt... AI data centers? ... does history repeat... that is the question.

Two hundred railroads went bankrupt in the 1800s. I don't  think the AI buildout will end the same way. The railroads were built on a hope and a prayer while AI revenues seem to be screaming. Watch my latest In The Know:

"The capex that's gone into AI exceeds that of railroads, exceeds that of other major industrial events in our history, electronification, telecoms, etc, highways, by far. So the question is where does it end?" @perkinscr97 on the state of the AI market

What can games like Diplomacy and 1830: The Game of Railroads and Robber Barons teach models about strategy and other work-related skills? We spoke to @goodstartlabs CEO @alxai_ (an alumni of @every) to find out.

The AI buildout in terms of percent of GDP is greater than the height of railroads, yet AI does not dominate the economy anywhere near as much as rail. In 1890, 1 out of every 12 men in America was employed in the railways, which used 56% of all horsepower across all machines!

In their quest to block a $72 billion merger between two of the biggest US freight railroads, a coalition of shippers and labor unions is trying to get President Donald Trump on their side

The most powerful periods of technological progress happen when two transformative technologies reinforce each other. We saw it with steam and railroads. We saw it with the internet and smartphones. Now it’s happening with AI and blockchain. Blockchain is uniquely positioned to power the next wave of autonomous AI agents through faster, cheaper, and more global rails. This convergence is already underway and will unlock massive economic activity. @cosmo_jiang @SquawkCNBC

Nebraska Senate candidate Dan Osborn has made rail policy a key topic in his fight to unseat Republican Senator Pete Ricketts in a state whose economy largely depends on railroads and their customers

Most transformational technologies get one shot: a boom, a bust, then a long rebuild. The internet followed that pattern. So did electrification and the railroads. Bitcoin does something none of them did, it (so far) resets every four years, giving investors a new chance to re-underwrite the whole asset class from scratch. BitGo's head of research, @GregCipolaro explains why that repeating cycle is exactly what makes this moment interesting.
