Here is a summary of the challenges Gemini faces, as documented by Newman:

1. Local results are worse: Gemini provides less useful information for local business queries compared to Google Assistant, lacking context and formatting.

2. Gemini can't take notes: Unlike Google Assistant, Gemini cannot take voice notes or save them in an app like Google Keep.

3. No-can-do on to-do lists: Gemini does not support adding items to to-do lists, a feature that Google Assistant handles efficiently.

4. Weather doesn't work right: Gemini struggles with weather forecasts, often giving incorrect locations, unlike Google Assistant which works reliably.

5. Turn-by-turn directions don't load: Gemini fails to provide direct turn-by-turn navigation, only offering a preview, whereas Google Assistant launches navigation immediately.

6. Music and podcast requests are YouTube-only: Gemini only supports YouTube Music, unlike Google Assistant which supports multiple streaming services.

7. Video (in)capabilities: Gemini cannot directly access streaming apps for movies or shows, only suggesting content with no direct links.

8. No photo search: Gemini cannot search for photos in Google Photos, a task that Google Assistant can easily handle.

9. Bye-bye to a useful news feature: Gemini fails to play or provide recent news effectively, unlike Google Assistant's useful daily news briefing feature.

10. No Routines: Gemini does not support the automation of multiple actions through Routines, a feature present in Google Assistant.

11. So much for Shortcuts: Gemini lacks the Shortcuts feature available in Google Assistant, offering no replacement for quick actions in third-party apps.

12. A slower experience: Responses from Gemini are slower by a second or two compared to Google Assistant when answering queries.
