Since you're probably already wondering how this work's from a privacy standpoint, Google says that message data is scanned locally, while some of it is shared with Google when taking a suggested Assistant action in Messages.
Google Assistant on its KaiOS-run smartphones will soon start supporting voice typing for the ease of sending messages on feature phones. This means a single press will trigger the Assistant, a double-press will bring up your Assistant's daily feed, and a long-press will trigger a sort of walkie-talkie function where you can speak to your Assistant and let go of the button when you're doing. It then gives the user an option to put the answer directly into the conversation thread. You will be able to get answers about such topics as movies, weather, and restaurants. It's not an Earth-shattering feature by any stretch of the imagination. For instance, we never see anyone saying "Hey Google, what's on my calendar?" or "what's the weather like?" Assistant will also be expanding its capabilities in the up-and-coming phone platform KaiOS.
The success of this will likely depend on whether the person you're chatting with is using SMS, MMS, or RCS.
Last, but not least, Google announced that it is working alongside Qualcomm and MediaTek to bring chip-level support for Android's Neural Network API and ML kit. Android Messages will be Google's primary texting app once Allo completely folds, and it's probably the best one there is. We can expect to see Digital Wellbeing, which is a really handy feature, find its way to more devices over the coming months.
Talking to Maps while you're navigating automatically updates the destination, and you can still do other hands-free tasks like saying "Hey Google, text mum that I'm running late" and "Hey Google, play my driving playlist". There's also dark mode, easier access to multimedia, and Material Design, just to name a few.
Google Maps is the American tech giant's navigation software that is available on Android, iOS and desktops. Thoughts about Android Messages?
