Google could replace the classic "I'm Feeling Lucky" button present since forever with the upcoming "AI Mode" option.

For example, the Camera has a “Classic Mode Switching” (this reverses the direction of mode switching). The Mail app got its Select button back, making it easier to select multiple emails.

If you open your Photos app, there is a good chance you will see that the classic search button on the bottom right is now a new "Ask" button. Tap on that button, and it opens Gemini.
