Soon you'll find that you cannot exist on the web without relying on third parties. Sometimes you'll even have trouble getting paid thanks to the painful existence of payment processors.

True, you can’t exist without 3rd parties. But you shouldn’t let them be your core moat/USP. Jasper is a great example, they depended too much on LLM access, then ChatGPT launched and ate the value. Using third party APIs is fine, but building a product whose core depends on them is suicide.
