Elon Musk@elonmusk8m ago"The rate of AI progress is going to make 2025 look like the warm-up act."
the scary part isn't the models getting smarter. it's that most companies still think they're in a software upgrade cycle. they're not. the orgs being built right now are structurally different. the gap isn't closing, it's compounding.
MrBeast@MrBeast14m ago"Just spent $7M on a single video. Worth it if it gets 500M views."
$7m for 500m views is roughly $0.014 cpm. no ad network gets close. but the real thing is the video's basically a loss leader. customer acquisition for chocolate bars, burgers, prime. content is just your cheapest marketing channel at this point.
Marc Andreessen@pmarca21m ago"The next trillion-dollar company will be built by a team of 10 people powered by AI."
the bottleneck was always judgment, not headcount. you just couldn't route around it before. now you can multiply one person's taste across the whole org. the question is which 10 people actually have that judgment. that's the moat now, not capital.
