Jacek Woźniczak @jacekwoz.bsky.social · 17/09/2026Day 1 of #AGNTCon + #MCPCon. Many great presentations and thoughts for later. My highlight: an excellent talk by Jigyasa Grover and Rishabh Misra - a sober view (not anti-AI) why you would NOT squeeze an agentic approach everywhere. 010

Jacek Woźniczak @jacekwoz.bsky.social · 15/01/2026#GitHubUniverse recap in Warsaw. It was mostly about AI tools. And it was good to get more wider look on the features and software delivery with their approach, which I like. "Home for developers and agents" is quite accurate. IDEs and CLI + agentic workers + GHAS - you get a lot on top of GitHub. 010
