The Week in Review (WiR) newsletter from TechCrunch covers notable tech events from the past week. Highlights include Disney's VR treadmill, OpenAI's fix for its "lazy" AI, and MIT's fast-charging organic battery tech. Apple's new stolen device protection feature, AI startup Rabbit's hardware, and the debate over launching apps for Apple’s Vision Pro headset are also discussed. The newsletter also includes a podcast section featuring discussions on Plural VC's new fund, Fantuan's partnership with Chowbus, Vroom's exit from the car-selling business, and developments at Brex.

This week, it covers the recent surge in tech startup layoffs, HPE's $14 billion acquisition of Juniper Networks, and the current state of fintech amidst staff cuts at companies like Brex. A bonus report reveals that Lamborghini has licensed a new battery tech from MIT that could potentially overcome the limitations of current lithium-ion batteries.
