Software tech in China is a different landscape. It's really common to reinvent the wheel in China. Almost every big name (Bytedance, Meituan, etc) have their own of everything with both office political and in house need reasons.
The thing is those stuff are so prevalent those in house tech have reach the point they are competitive. This doubles for quant firm like DeepSeek.
As much as @sama is not exactly "great" (World Coin is...ehem). The firing reeks political strife and anyone have enough days at any office knows what happens the next year at OpenAI will be anything but grandstanding for those "revolutionists" to stamp out any dissenting voice and fertile ground for the opportunists to use the chaos to make things worse. Most of the employee's prime objective will be navigating the political shitstorm than doing their job. The chance OpenAI stay as is before ChatGPT is little to none.
Better run for the lifeboat before the ship hits the iceberg.
I suppose with org like Google like this some overhaul is necessary. But I felt they are still playing politics when OpenAI/MS et, al. is murdering their profit margin.
