Being a developer for a number of decades has firmly taught me to never blindly trust computers. Even if the software is flawless (which is literally never the case), there's still the GIGO problem which your Apple Maps example demonstrates.

I once got fired because i upgraded a company's wifi network from a single apple wifi bridge (the residential one!) to a managed linksys or netgear deployment, and there was a bug in the firmware. I don't recall the bug, but it made the chief lawyer's apple laptop drop connectivity to their printer or something a few times the first day. I opened a support ticket, and got confirmation of the bug - at around 8PM, forwarded the email to my boss, and was fired the next afternoon.

what a crap company. They folded within 4 months IIRC, and listed me as the "financial contact" for the fiber optic internet links - got a bunch of nasty phone calls later in the year about needing to pay 5 digits in billing arrears!
