I've been impressed with the memory feature, but I do see how it could be dangerous, especially if you use it for hobby projects and serious projects. For work, I use ChatGPT to generate my weekly status reports for work, and that will come in handy when doing my annual review or updating my resume. But I would not want that context to spill over into a personal project
My status reports are pretty benign and I keep it generic: "solved a P2 relating to Java GC by allocating more memory" or "created a powerpoint slide deck outlining the benefits of on-prem versus adobe cloud for AEM". Not worth creating a new account.
Timezones are tricky, but they're not that hard. This is just bad engineering.
