That’s your opinion and I find that some parts are arguable:
Pairing is done once when you get a new phone or a new gadget. So bluetooth paring is to bluetooth connection what smartphone boot-up time is to lauch time of apps (in terms of frequency).
Fingerprint sensors are much more secure (someone would have to cut your finger off, instead of simply stealing your phone).
We have those too, but I don’t think that many people use them. There are location-based apps that can do the same, as well as QR-code approaches that are accessible to many more devices (they only need a camera).
