5. AI Contribution to GDP Growth-Morningstar
Preston Caldwell MYTH AI Isn’t a Major Contributor to the US GDP Growth
The third myth is that AI isn’t a major contributor to recent US GDP growth. This may sound odd, because the naive view is “of course it is—look at the hundreds of billions being spent on data centers.” But Goldman Sachs economists argued that AI-related investment in 2025 was offset entirely by imports, leading to zero contribution to GDP on net. This view is now perhaps the consensus among more sophisticated observers. But we think it’s missing the full picture.
We estimate that, as officially measured, AI investment contributed 0.4 percentage points to real GDP growth in 2025. And that contribution would’ve been 0.6 points without the Bureau of Economic Analysis undermeasurement of IT equipment investment.
Where does the view that AI’s contribution to GDP was zero in 2025 get things wrong? First, it assumes the official figures are correct. But even granting the official figures, there are two other mistakes. The zero-contribution view neglects the components of data center investment that correspond to non-IT equipment and structures. And it neglects the fact that AI services spending is capitalized as intangibles investment in the national accounts.

So, AI is providing a massive boost on the demand side of the economy, considering this direct contribution, as well as indirect effects, such as the boost to consumption from higher stock prices.
There’s one more nuance to unravel, though: AI’s contribution to GDP growth may be offset by tighter monetary policy. If this is the case, AI’s main impact on the economy isn’t higher GDP growth, but rather higher interest rates. Then, AI won’t start having a major uplift to GDP growth until it shifts from being merely a demand shock to also being a supply-side shock. The latter will happen once AI starts boosting productivity growth, which, as we discussed, is probably yet to ramp up.

6. Nuclear Power Capacity To Jump 44% By 2036 As China Surpasses US
by Tyler Durden Global nuclear capacity is set to surge by 44% over the next decade as China topples the United States as the biggest nuclear power capacity holder and India will hike its capacity to boost energy security. These are the estimates in a new report by BloombergNEF, which sees total global nuclear capacity at 535 gigawatts (GW) by 2036, up from the 372 GW of installed capacity as of the end of 2025.
The world is projected to have as much as 535 gigawatts of installed nuclear power by 2036, up from 372 last year, according to the report released Wednesday.

9. White Lines on American Roads in 1950s Life Saver
WSJ By Ben Cohen In the 1950s, around the time Jonas Salk cracked the polio vaccine, a metallurgist named John V. N. Dorr became the champion of a different lifesaver: a white line on the right side of the road. The study found that Dorr’s line nudged cars away from the center line, into the middle of their lanes, and narrowed the speed gap between day and night. In other words, the study found scientific evidence that a single line could dramatically alter human behavior.

10. My Question—Brown U has 20% of Kids Getting “extra time” for Exams Due to Issues. Do They Still Get Extra Time While Cheating with AI
This chart should be a ‘wake-up call’ about AI cheating, Brown University professor says By Henry Chandonnet
Brown University professor Roberto Serrano told Business Insider that the “cost of cheating has basically gone down to zero.” Roberto Serrano
- Brown University professor Roberto Serrano saw scores drop between a take-home midterm and an in-person final.
- He suspects the students cheated with AI. “It’s certainly a wake-up call to the professors,” he told Business Insider.
- Serrano shared the exam scores. Some dropped from perfect scores on the midterm to below 20% on the final.
What feels off in this AI-generated summary?
Roberto Serrano’s class scored curiously well on the take-home midterm exam. When he suspected widespread AI cheating and made their final exam in-person, their grades tanked.
The Brown University professor teaches welfare economics and social choice theory. The midterm was administered from home after a shooter killed two students in December.
“The problem with this technology is that the cost of cheating has basically gone down to zero,” he told Business Insider. “It’s very easy for students to succumb to the temptation.”
When he told students that the final exam would be in person, many previously high-scoring students dropped out. Others who scored in the high 90s on the midterm scored in the 50s on the final.
Brian E. Clark, Brown’s VP for news and strategic campus communications, wrote to Business Insider that Serrano shared details with the university’s standing committee on the academic code on July 8. The committee “move forward according to its procedures.”
“Brown treats every allegation of academic integrity with the utmost seriousness,” Clark wrote.
The scandal has drawn interest across the internet, and particularly among those who work in tech. Y Combinator cofounder Paul Graham posted on X about it; two Google DeepMind staffers also shared their thoughts.
A chart of the data, which was first publicized by Inside Higher Ed, shows each student’s grades:
