Makes sense, since he's a media darling now.
For decades, the key to Buffett's success was that he only invested in businesses he thoroughly understood. But in the last several years as he gets closer and closer to retirement, he's clearly diverged from that path as he's been investing in very complex and often convoluted industries (banking and insurance) that are diametrically opposed to the kinds of businesses he made is billions from. He's become a media darling, especially since espousing what has come to be known as "The Buffett Rule", where people like him (except actually himself) should be made to pay much higher taxes than they currently do. He's on TV constantly now, and I'm afraid he's actually starting to believe the hype.
So I really don't write too much into this.
