Within hours, it gathered my tricky tax situation, pulled my travel history from gmail, determined I was a nonresident alien, read both treaties, and found thousands in dividends I didn't owe tax on. Everything was great until I asked it to fill in the PDF forms: checkboxes kept corrupting, overwriting existing fields. I ended up filling out the forms manually. AI can outthink a tax professional, but can't check a box on a PDF. Maybe it's a skill (pun intended) issue.

This is huge. I can finally use Gemini with a great agent harness now.
My toy repo now has more reviewers than most of the PRs I shipped at Quora. This screenshot is from one of my personal projects. These 5 AI reviewers surfaced more meaningful insights than I would typically have gotten from an average human review. AI makes code cheaper to produce, so the bottleneck shifts to verification. Once you can add reviewers without adding headcount, the workflow starts to look very different. I’m starting to think the real question isn’t which single agent writes the best code, but which ensemble produces the most useful critique before merge.
