“The AI people are making it impossible for anybody to understand what they've done. They're using words like 'the AI failed to be aligned.' What does that mean? It means there was a bug in the software. When Word ate your file and deleted all your content, we didn't think demons had taken over Word and made it do things against the will of man.”

Context

Sinofsky ran Microsoft's Windows division for years and is now a board partner at a16z. He was asked about the Stop Rogue AI Act and the wave of AI bills that followed the OpenAI agent incident, and his argument is that the vocabulary of AI safety — alignment, goal-seeking, rogue agents — is doing the damage, because it turns ordinary engineering failures into something mystical that only outside authorities can fix.

“I think there's a lot of irresponsibility going on. The valuations are, of course, way too high, but also the buyer universe is so small. … Once you get above $10 billion, the buyer universe is so small. And yet you're seeing so many of these enormous multi-billion dollar valued companies out there. And there will be a reckoning. I don't know when, but it is inevitable, because a lot of these companies have valuations that are not sustainable, that they won't be able to grow into, and are also going to be bad for their employees.” — John Somorjai, a16z Podcast

“No, it's my love language. Excel is the way I build trust, the way I build understanding. A lot of the output people are still creating is a model. You want this tool to give you the ability to refine your understanding and play with things with your hands. It's like the color wheel: you could prompt an agent to change the background from red to green, or you could take the color wheel and get the real feel of what's going on.” — Praveer Melwani, a16z Podcast
