Nonsense. Most of the underlying tech that OpenAI relies on was in fact pioneered by Big Tech companies such as Google, Meta etc. So if Big Tech companies didn't want to make breakthrough bets, how come they invented the stuff? It's a self-refuting argument.
They sat on the tech for other reasons (fearing bad PR, excessive regulatory oversight) which OpenAI didn't have to worry about since they are small. That's why they released ChatGPT. Being small has its upsides. Well, I suspect that may now also slowly be changing as they are getting more and more integrated into MS.
P.S. Tsinghua has an LLM model very similar to ChatGPT's.
They published papers and built prototypes, while Open AI built an actual product that's revolutionizing the industry, which they are now playing "fast follower" on. That's the difference.
I recognized in that very post that Google, Microsoft, etc. have the *capability* to develop the technology but don't, for various reasons. The biggest of which is that, as large, public corporations, they aren't willing to invest in high risk products, choosing instead to focus on sure bets.
But with that sort of mentality, you will never be first, and being first is important due to first movers' advantage. Google may still be able to over take Open AI because of its natural platform advantages (Android, Google Search), but if it was any other company, it'd have been game over as ChatGPT is already in production and hundreds of millions are already using it. This is why Google declared "code red" the moment ChatGPT released. They knew how disruptive a technology it will prove to be and that if they don't match within a short amount of time, they'll lose the market.
As China, you want to be on top of these AI technologies. Not just a "fast follower," but a leader, like Byte Dance was in the social media space.
For that, you'll need start ups with a lot of energy and ambition. Fortunately, China has seen the rise of such start ups in other fields (electrical vehicles, social media, mobile games). So there's hope it'll manage in the AI space, too, though the US is doing its best to stop it (by trying to ban Western investors from investing in Chinese technology start ups).
