Just tried Firebase Studio. And just like IDX before it, I have full confidence that Google can make good if it keeps at it, but it’s just broken now. This AI gold rush leads to so many half baked products being launched way too early.

There is a lot of (justified) of excitement about MCP, but just like most function calling approaches, I think it has a severe limitation at the moment, and I am kind of of flabbergasted why I am the only one that is bothered by it. The problem is that when you define a tool

Spending some of my Saturday pair-programming with @GeminiApp 's new gemini-2.5-pro model in @cursor_ai. So far so good! Funny though how each model has a different style (e.g. in comments it generates). Gemini really seems to like putting *** in comments for some reason.
