Yeah Also people say "oh what if fly-by-wire fails" well what if traditional hydraulic controls fail, which has happened plenty in the history of commercial aviation Everything can and will fail at some point No redundancy is redundancy enough in some %0.xx of cases. You can always reduce the number, but never make it 0

The reliability of software is so bad this is an absurd comparison.

  This is a safety standards issue not a "software" issue. Standards for airplane software are very high Most planes have been fly-by-wire for decades and aren't regularly falling out of the sky

    Software is much easier to break accidentally than a valve.

  I work for a medical device manufacturer, and software absolutely can be designed to be just as reliable as physical systems, but the development and testing process looks completely different than a developing a mobile app. Things slow WAY down: if you want to change one line of code, it'll take literally weeks before it makes it to a production environment because of all the testing, documentation, justification, and human approvals. I imagine flight safety systems are subject to a similar level of rigor.
