🇪🇺🤖The #EU's proposed #AIAct wants humans to oversee #AI generated decisions. Is that a good idea?

🚨In a new @ZEW Policy Brief I explain all the reasons why it isn't and what should be done about that.

Vergangene Woche waren @JohaWa, @seb_waitforit und ich in #Berlin um zu diskutieren, wie die im #AIAct vorgesehenen #KI-Prüfungen umgesetzt werden sollten. Quintessenz: Das Design von Anreizen und Koordinationsmechanismen ist sehr wichtig für verlässliche Prüfungen. (1/4)

Great keynote by @BedreOzlem on Hybrid Marketplaces, Competition & Regulation at the @ZEW #ICT Conference 2023!

[The Parliament Magazine @Parlimag]

The evidence that humans are often poor supervisors of AI systems has been mounting in recent years.

The EU’s AI Act should acknowledge and address this reality, argues @JohaWa of @ZEW. https://t.co/mWOtXsSLxP

[Johannes Walter @JohaWa]

The #AIAct is overly optimistic about our ability to recognize and prevent poor #AI decisions... 🫣🚨

I wrote an opinion essay on the #AIAct for @Parlimag
on why that's a problem and what to do about it.

Check it out! ⬇️⬇️

Can police 👮, doctors 👩‍⚕️, hiring managers 🧑‍💼, ... humans be trusted to correct wrong AI advice? 🫣

[Luca Bertuzzi @BertuzLuca]

The EU's #AI Act heavily relies on human oversight to keep automated decision-making in check. But to what extent people are too lenient or too critical over algorithms remains an under-discussed subject. An interesting take from @JohaWa on @eaTechEU.
