My suspicion is that it's a reflection of how people like Altman want to be treated. As an European who worked with US companies, my experience with work communication there can only be summed up as being heavily biased towards toxic positivity. Take that up another 3 egotistical notches for CEOs and you get the ChatGPT tone.
I've once heard the company mandated more positive tone. To avoid words like "issue".
Not an issue, it's an opportunity! Okay, we have a critical opportunity in production!
This is definitely true, and is something that I've noticed that really annoys me. I have noticed that it varies quite a bit by region and industry, so not universal to the US or monolithic. The west coast of the US seems to be the most extreme in my experience
For a good example, just look at how Google does "support." It's just robots doing shoddy work and screwing over people. Can better compensated and organized human support team do better? Of course, but the rich execs don't want to spend a penny to help people if they can get away with it.
