Buffett has long moved past the stage of his/Berkshires life where he focuses on rate of compounding. He's implied he focuses more on not losing money (and making Berkshire less volatile) in recent years due to 1) Number of older people holding Berkshire for decades and relying on it to fund retirement and 2) probably also influenced by the amount of shares held by various charities (Buffett cares that those shares will help fund causes that will make a different; he doesn't want a situation where they need to sell at a low price). Munger even said as much toward the end of his life that you basically need to hold big tech to just match the S&P, and Buffett implied as much as well (he's repeatedly said big tech is good business and you can run them with zero capital). Berkshire is good for capital preservation and will probably vastly outperform bonds and a more conservative stock portfolio, but with how the company is weighted, its highly unlikely it will be able to keep up with the S&P going forward.
