Ha! That's a funny observation. People are indeed often skeptical about financial algorithms, but trust autonomous systems for other things like driving their cars or controlling traffic signals in the streets. It's just human nature to be reluctant when it comes to putting our finances in the hands of something over which we have no control.
As for having an automated central bank on one's phone, that sounds like a great idea already being implemented by various fintech startups around the world. And regarding Bitcoin, well we all know there are no greater believers than those convinced by themselves - keep on hodling that Bitcoin!
