Why did Sora quietly shut down? 🚫

It's not because of technical issues; it's due to hitting the "physical wall."
A hard-core economic calculation:
💸 Annual cost: $5.4 billion (computing power consumption)
💰 Annual revenue: $2.1 million (C-end income)
📉 Gap: 2000 times
When the physical marginal cost of technology cannot be reduced with scale, capital will ruthlessly cut it off.
OpenAI's path:
Become an all-knowing, omnipotent god → Bottomless computing power → Cost/revenue gap of 2000 times → Shutdown
Chinese companies' path (MiniMax/Haijia):
Create limited reality simulators → Focus on short dramas/e-commerce → Cut 95% of static visuals → Costs reduced to a few cents
This is the victory of "energy efficiency ratio."
On a resource-limited planet, the highest form of intelligence is not omnipotence but survival efficiency.
