Or just runs out of batteries and you don't have a charging cable. Maybe you could ask a stranger for help, but you're in a country where most people don't speak your language. Or maybe people do speak your language, but you have a phone with a charging port that isn't standard in the country you're in. Also, you're about to miss your flight.
I think we can all agree that edge cases will always exist. The question is does this system make those cases better or worse. What's the backup in case the first-line system fails? You go talk to the airline agents and get a paper boarding pass printed?
The facial recognition system I'm much more wary of. Will it recognize you if you are coming back home with a black eye (happened to me one time)? Could your doppelganger cause confusion with the check-in system? Is this system significantly more convenient for the traveler that it's worth putting your biometric data into a database that could potentially be appropriated for other purposes?
The language used here ('obsolete') strongly hints at making this the primary case, with any secondary option deemed inferior. It wouldn't surprise me if using a paper boarding pass will just flag you in the system for extra checks.

I’m a Global Entry member. I am already in all the databases ever, because I’m a doctor, so I just said f it and signed up. The facial recognition systems used by the US government- - if they get a well-posed picture of you (presumably with a lot of 3D detail) - are absolutely fantastic. I don’t even pull my passport out when returning to the US. I get a picture taken at a kiosk, I walk up to the line on the floor, and the agent says “you’re good, Devilbunny”. That’s it.
