Today's Take

The release of Gemma 4 31B has transformed "local deployment" from a compromise option into a viable path—a pragmatic route with mid-sized parameter counts is taking shape. Meanwhile, Buffett's "hold and watch" stance after stepping down creates tension with signals of AI-spawned new roles: extreme caution on the capital side versus radical change driven by technology. When models become smaller yet stronger, jailbreak tools escalate, and new job categories emerge simultaneously, it signals that AI is moving from the showmanship phase into the deep waters of real-world implementation. The key question is: how far can this wave of "jailbreaks" run?

Event: Workplace Discussion - @left7410 - It's 2026, surely there aren't still programmers not using AI? Although I don't use it that well either, I won't write basic CRUD myself anymore. I know posting this will get me flamed, and I don't feel superior just because I use AI—I'm just a newbie. I'm just struck by how divided this era is.

2026.3.31 Buffett Interview After Stepping Down: Holding $350 Billion, No Rush to Buy the Dip

Event: I assumed Buffett wouldn't speak publicly after stepping down, but surprisingly he gave a rare interview to CNBC on March 31, covering topics including restarting the lunch auction, market investment, the Middle East situation, Epstein, Bill Gates, and political parties.

Translation provided by Doubao; I only calibrated some content and removed repetitive filler words to make it smoother and more efficient to read.

Watch Signals

Watch three lines: First, whether mid-sized models like Gemma can establish a "local-as-a-service" commercial closed loop; second, when Buffett-level cash reserves will make their move—this is a bellwether for shifting risk appetite; third, the hiring growth rate for "AI-collaborative" positions, which reflects real penetration better than any hype. Technology paths, capital movements, and employment signals—only when all three resonate do we get a sustained trend.
