The people working there would know if they were getting close to AGI. They wouldn't be so willing to quit, or to jeopardize civilization altering technology, for the sake of one person. This looks like normal people working on normal things, who really like their CEO.
Your analysis is quite wrong. It's not about "one person". And that person isn't just a "person", it was the CEO. They didn't quit over the cleaning lady. You realize the CEO has impact over the direction of the company?
Anyway, their actions speak for themselves. Also calling the likes of GPT-4, DALL-E 3 and Whisper "normal things" is hilarious.
