> Cars, phones etc all have to do the thing they're designed to do before they're sold to consumers. Do you mean that someone individually uses each product sold? I don't think so. Things wear down in use. It's just reality. Not only does the market value drop, but accounting systems recognize it through depreciation. You've tried to redefine 'used' as superior reliability, but that's only in the rhetorical world where 'war is peace', 'freedom is slavery', etc. There is uncertainty to brand new, untested technology, but that's not what we're talking about. There is uncertainty to a more limited extent in unused individual products, but I've already addressed that. I don't know what team you think I'm on?
