I think accelerating that timeline is a good thing as I think he will be better than anyone who came after to direct how the funds as applied.
Appears to be more along lines of approval from others, which is a type of self-promotion if you will. IMHO a true do-gooder would go about his philanthropy/help/charity with zero publicity and would actively shun any.
Steel-manning: Gates has run a deliberate PR campaign for decades to rehabilitate his reputation. In the 80s & 90s (before the Gates Foundation) he was known as a ruthless corporate tactician who crushed competitors like ants and earned a federal antitrust suit against Microsoft. Prior to his divorce he had a widely-publicized affair with a subordinate. He befriended Jeffrey Epstein and appeared in his flight logs after Epstein had already been convicted of soliciting prostitution from a minor. (Gates has worked very hard to distance himself from Epstein since then - another example of the PR machine at work).
Someone who wants to paint the least charitable picture possible of Gates could factually describe him as a cutthroat businessman and a philanderer who associated with a pedophile on at least a few documented occasions. And that's ignoring the nuttier Gates conspiracy theories (e.g., Covid microchips).
Sure, everyone knows him. But he'd rather be known as a voracious reader who fought polio & malaria and provided drinkable water to millions. Not a bad use of his billions - what else could he spend those on that would materially affect his life?
