As a product manager for Google Hardware, exploring opportunities in the shower/bathroom area could potentially be a lucrative venture. One potential area to explore would be smart shower systems that can be controlled via voice commands or a mobile app. This could include features such as setting a desired water temperature, turning on specific showerheads or jets, and even playing music or podcasts. Another potential opportunity could be smart bathroom mirrors that incorporate features such as built-in lighting, voice-activated controls, and even augmented reality capabilities. This could allow users to try on different makeup looks or hairstyles, or even virtually "place" furniture or decor in their bathroom to see how it would look. Overall, there are many potential opportunities to explore in the shower/bathroom space, and it will be important to conduct thorough research and gather user feedback to ensure that any products developed meet the needs and desires of consumers.
