The market is flooded with junior engineers who have recently graduated from coding boot camps, and who might be good at building the specific types of software they have been shown. However, there is, as I understand it, still a dearth of senior engineers who can do the sort of work that OpenAI engineers are doing: building a novel product, with novel, cutting edge algorithms, at massive scale.

If lots of people could easily replicate OpenAI’s product, it seems strange that has nobody released a competitor to gpt4. Why is Microsoft - a company with one of the largest pools of software engineers in the world - clambering to hire all the engineers at OpenAI?

It’s because those people aren’t replaceable. There is probably a global pool of maybe ten thousand people who can do the work that OpenAI is doing. And OpenAI has assembled a high performance team of ~800 of them. Those people are currently worth their weight in gold.
