Agreed—I spent the 90s idolizing Jobs and despising Gates. But today I have deep respect for Gates and the way he's using his wealth as a positive force in the world. Jobs had better taste and was a more effective product leader, but I'm sorry to say that he sucked as a philanthropist. It's disappointing that he spent ANY of his mental energy at the end of his life building that dumb $100M yacht, rather than focusing on his legacy.
I’m making a stretch to find an answer, but there’s an argument to be made to putting great works of art and beauty in to the world counts as an act of bettering humanity. Look at The Vatican for an example. The patronage of that wealth concentration gave us many of mankind’s greatest achievements.
So if you consider Jobs’ boat or Apple Park or the fact that 700M people hold a literal masterpiece of design and engineering in their hands in order to send nudes and memes to each other a work of benevolence then it makes sense.
