    Our car window was smashed and my backpack stolen. Men rolled up in a car wearing ski masks and jumped out. Us and our four kids a few feet away. Laptop, phone, etc all gone. The city is suffering. This is not normal and we should demand better.

    In March 2021 I contemplated leaving @OpenAI to start a company around the ideas that open source and open research were going to win. I decided it was too early but obviously that's no longer the case. Here was my thinking at the time. Who is building this? I Want to help them.

    On the one hand, I feel for @ylecun and Meta/Google researchers. Not seeing your research released in usable products due to big tech bureaucratic bs would be hard to stomach. Yet what they have released has been so fumbled it suggests a profound ignorance about shipping product

    Replying to @Fraser and @ylecun
    This wasn't meant to be controversial. I'm saying the same thing as LeCun: "It's nothing revolutionary, although that's the way it's perceived in the public," the computer scientist said. "It's just that, you know, it's well put together, it's nicely done."

    While building ChatGPT at @OpenAI I was repeatedly told by our internal teams that our corporate docs were the "Crown Jewels" of the business. I get it. Nobody trusts AI. That's why Spark is excited to support credal.ai in building the security layer for AI

    The Financial Times wrote that "OpenAI ranks as one of the most unusual organizations on the planet". I’ve been here just over a year and I must agree! Here’s a thread.
