Generally, these cloak-and-dagger companies just vanish especially industry where is fierce competition because cloak-and-dagger stuff takes just too much energy from the north start. I would not be surprised if 2025 GPT-5 still is not out and OpenAI just drops the whole model + number concept and just starts calling it to gpt.
Calling it GPT just like Apple calling it "the iPad" is something you can do when you basically have no competition. OpenAI faces competition from all sides so they need the numbering game for now.
Hate to break it to you, but this is how C suite looks like in every bigger company, you don't even need to go multinational or S&P 500.
Now I am not saying everybody is exactly same, there is variation, but within the shades of grey. Same as politics - think about all the hard battles they had to fight for decades, how could a decent honest person not only survive that but also come out on top of all others? At the end, with right kind of eyes you can find pretty simple logic everywhere.
