@GoogleAIStudio That's Nice

@sachinyadav699 Healthy food

Ending my day like this…

@ishanxtwt X is best, no alternative

Name a better alternative to X I'll wait.

@alohaproxy @aradotso Agree

Hot take: The future of software engineering isn't solo AI. It's multiplayer AI. Humans and agents working on the same codebase together. @aradotso One day this workflow will feel completely normal. Agree or too optimistic?

@stats_feed Nice to know,every country should follow it

🇯🇵 Kansai International Airport in Japan averages 15-31 million passengers a year and it has not lost a single piece of luggage since opening in 1994.
