To be honest, I hate takes like this. ChatGPT, which basically revolutionized the whole AI industry and the public's imagination about what AI can do, was released not even 15 months ago, and since then they have consistently released huge upgrades (GPT 4 just a couple months later) and numerous products since then. I still haven't used another model that comes close to GPT 4. But since it's been, say, all of 23 hours since OpenAI released a new product (memory) they're "losing their luster".

The same nonsense happened with Apple, where like a month after they first released Apple Watch people were yelling "What's next???!!!! Apple is dying without Steve Jobs!"
