Hello. This is Alistair Barr, Business Insider’s global tech editor. We had a big week in Big Tech, so we’re breaking it all down for you.

Google: I attended Google’s I/O conference on Tuesday. It’s the quintessential Silicon Valley experience. This year was no different: The $2 trillion corporation kicked off its most important event by giving an AI music tool to a DJ dressed in a rainbow bathrobe. Check out I/O highlights.

Google finally knows where it’s headed, after a decade of wayward moonshots and incremental Search improvements. BI’s Hugh Langley explains Google’s big bet on “AI agents.” What changed? Read on below.

OpenAI: This startup awakened the beast. Google was cautious, but OpenAI cleared the way by releasing ChatGPT and getting sued left, right, and center. Google is a fast follower, but with years of AI research and infrastructure to deploy. “Google was built for this moment,” CEO Sundar Pichai said.

On Monday, OpenAI slipped in an event of its own — an attempt to one-up Google again. It didn’t work this time. Read our recap of the startup’s conference.

Apple: It looks woefully behind in AI now. Tim Cook is an incredible CEO, but he’s not a product genius. He needs something new more than ever.

Amazon Web Services: Amazon is also behind, although AWS is a great platform to compete for the AI spoils. The cloud business got a new CEO this week. Get to know Matt Garman.
