I think I like the direction they’ve been going in lately.

You can do that today with the FUTO keyboard lol. It uses a small language model for predictive text.

Brave Search, not because I like the company and their crypto/ai shenanigans but they have some nifty features and (supposedly) an independent index.

GrapheneOS has sandboxed Play Services which basically means they run just like a normal app on your device and you get to choose the permissions they get. My bank's app works with it too (no GooglePay tho). It does require you to get a Google Pixel phone though, which might defeat the whole purpose for some.
