Is Mark Zuckerberg still obsessed with efficiency? Check Meta’s WiFi password.

• The social-media giant held its big Meta Connect conference in Silicon Valley this week.
• Mark Zuckerberg is spending heavily on AI and AR technology.
• Is the CEO still obsessed with efficiency?

2023 was Mark Zuckerberg‘s “Year of Efficiency.” He chopped tens of thousands of jobs, eliminated management layers, and took other drastic steps to save Meta money.

That effort continued into 2024 as the Meta CEO whittled down VP ranks and took more cost-cutting steps.

However, Meta has also gone on a spending bender for AI, GPUs, and the data centers needed to compete with OpenAI, Microsoft, Google, and Amazon.

So, is Zuckerberg still obsessed with efficiency?

The company dropped a big clue this week at its Meta Connect conference in Silicon Valley.

Tech reporter Pranav Dixit attended and noticed that the WiFi password for the event was “effici3ncy.”

Dixit posted about this on Threads and Zuckerberg liked the post.

That’s a big hint that the Meta CEO is still laser-focused on keeping his company’s costs in check, even as it presses on with pricey AI projects such as its Llama open-source AI models.

Business Insider asked Meta for comment on Thursday and didn’t get a response.
