To me, this is striking:

“I had previously assumed a 10-year depreciation curve, which I now recognize as quite unrealistic based upon the speed with which AI datacenter technology is advancing,” Kupperman wrote. “Based on my conversations over the past month, the physical data centers last for three to ten years, at most.”

In his previous analysis, Kupperman assumed it would take the tech industry $160 billion of revenue to break even on data center spending in 2025 alone. And that’s assuming an incredibly generous 25 percent gross margin — not to mention the fact that the industry’s actual AI revenue is closer to $20 billion annually, as the investment manager noted in his previous blog.

Meaning that currently his guess is that at current revenue, it'll take 8 years to break even... So maybe they'll get two years of profit at max, or be underwater by five years and $100 billion. Current revenue is going to change, but they'll have to triple it in short order or be at risk... And that seems somewhat unrealistic with the lack of success in the AI products.

From https://hbr.org/2025/08/beware-the-ai-experimentation-trap apparently 95% of AI projects piloted by businesses have produced no measurable return.
