## What people warn about

- Keystroke tracking seen as creepy (3 comments): "Systematically reconstructing a timeline of every keystroke that went into a project, then immortalizing this timeline into a VCS, that's the creepy part." ([source](https://news.ycombinator.com/item?id=49189031)) "interesting concept to toy with. I'd pay more attention to "micro commits" as the idea more than the keylogger" ([source](https://news.ycombinator.com/item?id=48496034)) "gives micro-managers the data they need to micro-manage you" ([source](https://news.ycombinator.com/item?id=49188218))
- Locks users to Zed harness (2 comments): "it actually forces you to use their editor/agent harness which is a no go for me" ([source](https://news.ycombinator.com/item?id=49758135)) "it actually forces you to use their editor/agent harness" ([source](https://news.ycombinator.com/item?id=49756716))
- Mostly useful for agents, not humans (2 comments): "This feels very useful for training agents but almost completely useless to humans?" ([source](https://news.ycombinator.com/item?id=49188512)) "Not convinced DeltaDB is useful for humans directly but assume new and interesting interfaces can arise from the abstractions it provides." ([source](https://news.ycombinator.com/item?id=48494939))
- Seen as AI slop and hype (3 comments): "well polished slop, but ultimately slop at the end of the day" ([source](https://news.ycombinator.com/item?id=49561610)) "It's obviously AI copy, and a huge negative signal" ([source](https://news.ycombinator.com/item?id=49190475)) "It's not just a step, it's a leap towards real productivity that your agents will actually use!" ([source](https://news.ycombinator.com/item?id=49190922))
