What's this about?
Ethan Mollick gave Astra tens of thousands of emails, his writings and his calendar; over five days of unattended work it built a multi-gigabyte cross-linked personal wiki.
What exactly makes "unattended" the key word?
Not the wiki — the duration. Agents historically degrade over long runs: they drift, lose the plot, compound errors. Five productive days without correction is a capability data point that no benchmark measures directly.
Why is this worth noting?
It's also a maximal-trust demonstration: full archive access and days of autonomy. The output is impressive precisely because of what was handed over — Mollick himself makes that trade explicit elsewhere in today's digest.
