Apparently Larry Ellison recently became the richest person in the world, although they're also saying that Elon Musk rebounded after a few hours to keep the title. Still, they're both one of a very small elite. The wealthiest men who haven't paid to have their names removed from the public record.
Will Ellison use his wealth more for good than evil. I wouldn't count on it, given that his son is looking to further merger the already thoroughly mergered Hollywood.
But the weird thing from my perspective is how Ellison got there with Oracle. Don't get me wrong, Oracle seems from the outside like it would be quite profitable. But look at Microsoft. They took over the operating system business with MS-DOS in 1981, when the personal computing era was just getting underway. Windows came a few years later. I use Windows. Most people do in some way, whether they like it or not. And the Microsoft Office suite that includes Word and Excel is pretty much universally used. So I know how I've put money in Bill Gates's pocket. Anything I've done to make Ellison richer has been invisible.
