Old age is hell, anon. If you don't take care of your mind, you end up becoming a hasty and greedy walking carcass, just like them.
That also comes from becoming addicted to the gains from one's success. Things like money, luxury and so on. A person exposed to those becomes lazy and arrogant. Mixed with old age and the greed that comes with it, the person becomes literally rotten, thinking that nothing could ever fail.
Another example: Yuji Naka. After Sonic's initial success, the idiot went on a buying spree and got himself things like Ferraris and a big house. Then the money started to run out, and the idiot thought that he could just make anything he wanted, that people would somehow buy en masse just because of his name. He ended up in jail after failing many times over and over, but never once he changed that arrogance and greed.
