Google Search Just Got a Brain: Why the New Gemini 3.5 Flash Update Changes Everything

I know this sounds like press release fluff, but I tried it myself and my brain actually did a double-take. Google just changed how Search works. The entire thing is now powered by Gemini 3.5 Flash. It does not spit out a list of links anymore. It builds a custom page summarised for you. With follow-up questions.

And it lets you deploy information agents to run background tasks while you go home. That is the biggest change in Search in over 25 years. Google said that. Not me. I am still trying to get my head around it.

I was writing a campaign brief for a client on Tuesday. Stuck on the third paragraph. I typed my query into Google. The old way would have given me ten pages. I had to click, read, click, read. This time? A single page popped up. It had the key points. It had the links if I needed them. It had a box for follow-up questions.

I asked, “What are the top three trends for eco-friendly packaging?” The page updated. It was fast. It felt like talking to a person who had already read the report. I felt a little guilty. Like I was cheating. But then I thought. No. This is the point. Save time. Do the work.

Then I tried the agent feature. I told it to “find pricing for three suppliers by Friday” and “summarise the results”. It went off and did it. In the background. I made coffee. I checked my phone. The job was done. My inbox had the summary. I did not write a single line. I just had to trust it.

I am not sure if I trust it enough. I worry about the data. I worry about the accuracy. But I used it again today. For call transcripts. I asked it to auto-summarise the call with my team. It did. It pulled out the action items. It pulled out the blockers. It was right. It was useful.

Here is what matters for you.

• For marketers: Generate campaign briefs in half the time. The summarised page gives you the trends. You just fill in the gaps.
• For analysts: Sync inventory with Shopify using an information agent. The agent runs the task. It sends the report. You do not click a button.

I still feel a bit unsure. Is this the future? I do not know. I just know it works. Right now. On Tuesday. With my coffee.

Okay. I am done.
