NVIDIA responds: "roadmap unchanged." ↳ Talking point: The first crack in the AI hardware narrative — even with NVIDIA's denial, the market reaction shows how fragile valuations have become.

🧠 Thought Leaders & Research

Nobel laureate Acemoglu et al.: population decline may actually boost prosperity — New paper challenges the prevailing "demographic doom" narrative. Research finds workers and firms adapt by leveraging technology to compensate for labor shortages; per-capita output gains fully offset population decline. ↳ Talking point: A direct challenge to "population crisis" orthodoxy — if Acemoglu is right, Japan, Korea, and China's demographic anxiety may be overblown. · Sina Finance

"Did you hear? SpaceX made it into the Nasdaq 100 just 15 days after listing — $35 billion in passive funds forced to buy. Musk now has Tesla, SpaceX, and xAI all running simultaneously. This game is enormous."
"Microsoft just cut 4,800 people, a fifth of Xbox — not because they're broke, but to move people from gaming to AI. Do you think Xbox will still exist in five years?"
"Nobel laureate Acemoglu published a paper arguing population decline is actually good — fewer people means higher per-capita output because it forces tech adoption. Does this logic hold up in the AI era?"
