It's a joke about how Google has released/cancelled/renamed many messenging apps.

It is not very good though.

Gemini is pretty good, And it does one thing way better than most other AI models, when I hold down my phone's home button it's available right away

That's a shame on Google, Apple, Samsung, etc. Voice and other activation methods should be open to any app that claims to be an assistant. An ugly way of "gatekeeping".
