I've really embraced biometrics now that I understand that they're effective for certain use-cases when properly implemented.

For example, the primary threat model for my mobile device is a combination of shoulder-surfing and theft, because I ride a lot of public transit. So it's way more secure for me to touch the fingerprint sensor rather than constantly peck in my password while I'm being observed. A common criminal or homeless dude who steals/finds my phone won't know my password because I'm not revealing it, and they're unlikely to have access to my finger or its print.

If my threat model were different, say law enforcement/TSA confiscation or something, I might be more worried about walking around with fingerprint auth enabled. So if I head to the airport or enter some other high-risk area, I might consider disabling that, removing the sdcard and/or SIM card temporarily.

Biometrics as a way for my personal device to recognize my physical presence is mature tech, and useful for consumers in ways that passwords aren't.
