What’s next?

* Train newcomers to use AI responsibly.
* Automate reviews to reduce expert burden.
* Reward experts for mentorship, not just fixes.

Where do you see this happening in your field? #AI #Workplace #Innovation

5/6
Why it matters:

* Experts are a bottleneck. If they’re stuck fixing, innovation slows.
* Quality risks: AI can introduce errors that experts must catch.
* Burnout: Experts may leave if their role becomes only reviewing.

4/6
Beyond coding: This risk applies to any role where AI "helps" newcomers:

* Customer support: AI drafts replies → seniors edit.
* Design: AI generates layouts → experts refine.
* Legal/writing: AI drafts docs → seniors verify.

More output ≠ better quality.

3/6
The pattern:

* AI lowers the barrier → newcomers contribute more.
* But their work needs more fixes, overwhelming experts.
* Result: Experts innovate less, review more.

This dynamic could reshape any field where AI assists workers.

2/6
How we show this:

* Analyzed 2,755 open-source projects and 1,699 contributors before/after Copilot’s launch.
* Used difference-in-differences to isolate AI’s impact.
* Found: Experts shifted from coding to reviewing, while AI-assisted work needed more rework.

1/6
🚀 Our new study reveals a hidden cost of AI tools like GitHub Copilot: While less-experienced devs produce 43.5% more code, experts face a 19% drop in productivity as they shoulder the review burden.
This isn’t just about coding—this might also affect other work. Thread 👇 #AI #FutureOfWork

Earlier this year, we used less granular data as a basis to model the resulting dynamics. Such as periods of overordering of GPUs.

Will be interesting to see how this will develop.

When AI Hype Meets AI Reality: A Reckoning in 6 Charts Record capital expenditures and data-center planning are running up against the ground truths of physical infrastructure.

Excellent data provision and great visualizations by @mims.bsky.social on AI infrastructure. Bottom line: physical build cannot follow announced investments. By far. Bounded by grid capacity.

Iemand die weet waarom het in Nederland vijf maanden moet duren om verkiezingen te organiseren als de Fransen het binnen een maand kunnen en de Engelsen ook binnen een week of zes?

This is a huge moment of opportunity for any country which wants to poach talent by offering generous R&D funding, expanding universities, easy-access visas for researchers etc

(and a huge moment of stupidity for those, like 🇳🇱 , who are doing exactly the opposite)

Interesting analysis by @joristeer.bsky.social . Some of the examples can rely on strengthening and expanding the current industrial base. However, in many industries, it is an issue of redeveloping the ability to produce at mass scale, against affordable cost, and error-free. Tough process.

Eliminating or restricting OPT would not only be a massive blow to the ability of the US to continue attracting the world's top STEM talent, but also wipe out many graduate programs at universities that already have come under enormous financial pressure.

"Bindend voor alle partijen maar niet juridisch afdwingbaar". De goed-bestuur en betrouwbare-overheid club van @omtzigt.bsky.social laat zich opnieuw van zijn beste kant zien.

Seems the US Government is now also getting into auto companies' pricing decisions. Waiting for the first executive order on pricing (or was there already one on eggs?)

Blijkbaar hebben ze meer vertrouwen in de Zweedse wetgeving en bedrijfsvoering

Op zich wel handig dat ie de lijn stopzet nu er ook enorme tarieven op datzelfde staal worden gezet 🤷

The key skill that Europe lost over the past two decades is to industrialize the manufacturing of new technologies. Northvolt is a sad example.

"EU programs are geared towards the early stages of tech development – not to deployment. There is a dearth of support for the manufacturing stage."

Hogescholen versoepelen bindend studieadvies: 'Minder streng bij valse start' Veel hogescholen vinden dat een "valse start" van eerstejaars studenten niet keihard moet worden afgestraft.

Studenteninstroom daalt en hogescholen verlagen kwaliteitseisen.

Witnessing these and other insane tariff threats, indeed calling the bluff would be the best strategy for every single country faced by US tariff threats.

Het is wel handig dat die wet echt een duizend-dingen-doekje is. Ik vermoed dat hij ook zal helpen om de files te verminderen en de stikstofuitstoot omlaag te brengen.

OpenAI says it has evidence China’s DeepSeek used its model to train competitor White House AI tsar David Sacks raises possibility of alleged intellectual property theft

It is truly remarkable that a company that has violated the copyright of millions of authors to train its models claiming now accuses a new competitor of stealing its IP.
