Greg Abel moved to assure Berkshire Hathaway shareholders that he will invest wisely and manage the conglomerate¡¯s massive cash stake without the burdens of bureaucracy, as he seeks to win over those cautiously hoping he is a worthy successor to Warren Buffett.

Abel, 63, spoke at Berkshire¡¯s annual meeting in Omaha, Nebraska, four months after succeeding arguably the world¡¯s most famous investor as chief executive officer.

He must earn the trust of investors now enamored with technology and artificial intelligence, rather than Berkshire¡¯s collection of insurers, retailers and hard-asset businesses in energy, industrials and manufacturing.
