Mark Zuckerberg says that the developme=
nt of superintelligence is now in sight. He is extremely optimistic that su= perintelligence will help humans accelerate their pace of progress and begi=
n a new era of personal empowerment where people will have greater agency t=
o improve the world in the directions they choose. Meta's vision is to brin=
g personal superintelligence to everyone to help them achieve goals, create=
what they want to see in the world, experience any adventure, and grow to = become the person they aspire to be. It believes that the benefits of super= intelligence should be shared with the world as broadly as possible.
