I’m not sure what you’re arguing. That someone invented the iPhone and it went on to be a very successful product for a multi-trillion dollar company? The iPod was out for years before then. Before that there were portable CD players, before that were portable cassette players, and before that portable radios. Long before any of that people would set wood on fire and sing while playing instruments they carved from other wood.
Corporations do get things wrong plenty often. Successful corporations will not invest more than they can afford to on anything, and won’t mass produce a product that their user-surveys and number crunchers say won’t make them money. Sometimes those surveys and numbers are wrong, but a corporation doesn’t build a worth of trillions of dollars by making stuff and putting it all directly in the dump.
