Guarantee? That's one of the most important aspects of bothering to build out a platform: eat the ecosystem to add incremental value to the platform, bolster the moat.

The guarantee is that they will clone and extinguish most of the best bots/tools/services riding on top of GPT. It's what platforms overwhelmingly tend to do.

If your thing is a near-touch to GPT, depends on it, is of medium complexity or lower, and is very popular/useful, they will build your thing into GPT eventually.

On the flip side, if you're Salesforce and using GPT to augment something about a major product, you're not facing a serious threat of OpenAI trying to become the next big CRM company.

This process will work similarly to how it did with Windows, Google, AWS, etc.
