Getting ready to speak at the AI Summit in Copenhagen.
Telling my story of using AI as a software engineer on the team. Using Devin to build native iOS and Android apps 🎙️

Just gave a pretty skeptical talk on the use of MCP servers today.
It blows my mind how MCP was built without any security layer in the protocol.

You would never handover your physical access key to a random person you've never met before.
But people are happily handing over their credentials to AI with nothing but their untrained prompting skills for control?

🤯😱

iOS fakes an infinite rotating dial by just making a really long repeating list, cause nobody would ever scroll all the way to the bottom, right? 😂

@alexozun finally got around to watching your talk here. Truly fascinating stuff, and I learned something about non-Copyable types too!

Yet another GitHub Copilot workshop with more than 30 people done and dusted 🚀
I love to see the panic in people’s eyes when they realise how dangerous the use of MCP servers are. Especially multiple MCP Servers combined 🤯🔥
