No product is perfect, and certainly bugs/ faults exist that the software company/ mfg didn’t know about when they shipped it. But we also know from various lawsuits (like Pinto) that faults exist that were known before the product was released to the wild but they shipped anyway. I’ve been in the software business for 15 years and I’ve never been involved in a release that didn’t have open bugs on ship day, some we intended to fix later, some we never intended to fix.
Now one thing the software industry does that opens the door to extra criticism is we believe strongly in 3 levels of good enough to ship. The highest level, the level most people wish was the only level is medical software, medical software really does need to be nearly perfect, especially the stuff that’s embedded in medical hardware like those drug dispensing machines. Next is the “moves metal” level, generally what we’re talking about there some of the stuff in your car, elevators, airplanes, and missiles, the part of the software that moves metal in a way that could kill people needs to be pretty bulletproof, the rest though isn’t that big a deal (we’re OK with elevators occasionally putting you on the wrong floor, so long as it doesn’t go THROUGH the floor at high speed). Then there’s all the rest of the software, software that can’t possibly kill anybody, pretty much the quality target for that is not being sued, followed closely by not being embarrassed, everything beyond that is gravy.
LOL. I get it. I don't doubt it, either.
