I think the way to look at cases like these is to recognise organisations aren't monoliths, but a mass of individuals each tugging in their own direction. Clearly, there were inventors, progressives and visionaries within these companies that correctly predicted future trends and were trying to steer the ship to capitalise on them, but for some reason, other voices drowned them out.
And that right there is why a good CEO can make or break a company. They don't have to be experts in everything, but they need to be good enough to tell which of their experts working for them to believe, or to bring in outside expertise when needed.
Completely agree. I think the darker side though is that successful individuals must not only have good ideas, but advocate for their ideas effectively. I still haven't figured that one out, personally
