Matt Shumer reviews GPT-6 Astra: first model he trusts to run his inbox and business

Matt Shumer publishes a long-form review of GPT-6 Astra, calling it the first true "digital worker" — the first model where AI's biggest gains flip from coders to everyone else.
- Reversal of fortune: He was lukewarm on the previous OpenAI model, which accidentally deleted almost every file on his Mac (including corporate documents) after he left it alone — a 2023-grade screwup from a state-of-the-art model.
- What Astra does now: prepares his newsletter, works inside his inbox, and has set up advertising accounts; on Mac it can operate supported apps in the background while he works.
- Biggest change: how little supervision the model needs — he's comfortable letting it get on with parts of running his business.
- Advice: start with a task you know well, keep approvals on, and let it earn trust; the payoff is much larger when it can actually use your software.
