AI tools slow down expert developers

PLUS: How McDonald's AI was hacked by '123456' and OpenAI's plan to take on Chrome

Welcome back, AI’ers!

Here’s What’s On The Menu For Today

  • The AI productivity paradox for developers

  • McDonald's AI hacked with password '123456'

  • OpenAI's plan for an AI web browser

  • Amazon deepens its partnership with Anthropic

AI ON MY MIND

Happy Thursday,

A new study is challenging the long-held assumption that AI tools are an automatic productivity boost. Research from Metr found that for experienced developers, using AI coding assistants on complex, real-world tasks actually made them slower.

A fascinating part of the study was the gap between perception and reality, as developers believed they were significantly faster while the data showed the opposite.

By the way, I've been getting questions about how AI works in practice, so I'm launching a separate newsletter that dives deeper into real business applications and practical advice. [Click here if you're interested].

TODAY’S TOP STORIES

The AI Productivity Paradox

The Recap: A new study from Metr challenges the universal productivity gains promised by AI, finding that AI coding tools actually made experienced developers 19% slower on real-world tasks.

Unpacked:

  • The trial involved experienced developers working on actual bugs and features from large open-source repositories they contribute to, ensuring a high-realism setting.

  • A striking gap between perception and reality emerged, as developers believed they were faster by 20% when using AI, despite the data showing a significant slowdown.

  • This research highlights the difference between impressive benchmark scores and performance on complex, real-world tasks, suggesting a need for more diverse evaluation methods as outlined in the full paper.

Bottom line: This result highlights that effectively integrating AI into expert workflows is more nuanced than just adopting the latest tool. This methodology provides a crucial baseline for measuring future AI progress in settings that matter most.

McHacked by '123456'

The Recap: McDonald's AI hiring chatbot, managed by vendor Paradox.ai, was breached by security researchers who gained admin access with the password '123456'. The flaw, detailed on their blog, potentially exposed the personal data of up to 64 million job applicants.

Unpacked:

  • The breach stemmed from a stunningly simple oversight: a test account on the McHire.com portal was secured with the username and password “123456” and lacked multi-factor authentication.

  • Once inside, a second flaw allowed them to browse through millions of records containing names, emails, and phone numbers simply by manipulating applicant IDs in the website's URL.

  • In response, Paradox.ai acknowledged the vulnerability, confirming it was a dormant test account and announcing a new bug bounty program to prevent future issues.

Bottom line: This incident underscores that the biggest risks in AI adoption often come from basic human error, not complex model attacks. It's a critical lesson for companies to vet the fundamental security hygiene of their third-party vendors before integrating new technology.

🖥️ My Favorite AI Tool: Relevance AI

Relevance is my favorite AI tool right now (even more so than N8N).

Here’s why:

It’s an AI agent building tool that doesn’t require you to build out the logic using nodes. Instead, you use natural language to build out these agents. But the best thing imo is that you can build AI Agent teams.

Like agents talking to each other completing a goal until its done. It’s nuts. No other tool on the market is doing this. You have to check it out.

OpenAI Declares War on Chrome

The Recap: OpenAI is reportedly just weeks from launching its own AI-powered web browser, a direct challenge to Google Chrome that escalates the battle for the future of the internet.

Unpacked:

  • The browser plans to use a ChatGPT-style interface and its [Operator agent](https://openai.com/index/introducing-operator/) to automate web tasks like filling out forms or making reservations for users.

  • This news drops just as competitor Perplexity Comet begins rolling out, signaling a major industry shift from standalone AI search engines to fully integrated AI browsers.

  • A key driver is data—by owning the browser, OpenAI can gather web usage information to train its models, a resource Google currently controls and has reportedly refused to share.

Bottom line: The browser wars are officially back, but this time the fight is over AI-native experiences, not just speed and features. This shift could fundamentally change how we interact with the internet, moving from search-and-click to conversation-and-automation.

Amazon Doubles Down on Anthropic

The Recap: Amazon is reportedly considering another multi-billion dollar investment in AI startup Anthropic. This move deepens a strategic alliance aimed at challenging the dominance of Microsoft-OpenAI and Google in the AI arms race.

Unpacked:

  • The partnership goes far beyond capital, involving the ambitious Project Rainier—a 2.2-gigawatt data center—and the use of Amazon’s custom Trainium2 chips to train Anthropic’s models.

  • Amazon views Anthropic's structure as a 'public benefit corporation' as a more stable long-term collaboration, with Anthropic’s Claude AI already integrated into products like Alexa and Prime Video.

  • The move is being watched closely on a financial level, where Wall Street analysts forecast a potential 10.23% upside for Amazon's stock based on its aggressive AI strategy.

Bottom line: This isn't just a simple investment; it signals a deep integration of cloud infrastructure, custom hardware, and advanced AI model development. This alliance solidifies a powerful new force in the AI landscape, creating a formidable competitor to established leaders.
