Openai is a bunch of scientists. And their product is not exactly unique - all the major cloud vendors will have a chatgpt available soon. So openai won't copy for the same reason AWS can't copy all of its customers - presumably the ppl building the product are better at building that product than, like, a room full of scientists.

Sam Altman is not a scientist.

OpenAI and Amazon are two very different companies. Some companies are aggregators that focus on doing a bunch of things like Microsoft or Amazon. Others focus very heavily on doing one thing well like Netflix. And I think OpenAI is the latter type of company as opposed to the former.

Granted many companies start off as the first and transition to the second type of company but OpenAI is so far away from that you'll probably have a good 10-20 year run before that.

Same reason Amazon Prime doesn't work as good as Netflix yet Netflix is hosted on AWS

The platform works as well as netflix, it’s the licencing of content which is different

IMO Prime Video is a lot nicer than Netflix. Prime typically has almost any combination of audio/subtitle languages that I want. Netflix typically has only North American languages (English,Spanish,French), and usually only as /either/ subtitles /or/ a new audio track. I'm working on my Polish (because my wife is Polish) and my wife is working on her Spanish (because she's studying it as a hobby) and we frequently watch Prime shows with Polish "lektor" (it's not dubbing, just a guy interpreting the characters' English, which you can still hear) and Spanish audio, or vice versa. On Netflix we can usually find Spanish subs or Spanish dubs -- rarely both, and Polish anything even more rarely (even for shows that are natively in Polish!).
