Amazon had a product on day 1... particularly one that was unique and made a lot of sense for the moment it was introduced.
If someone else can achieve the same output as OpenAI at a similar price, they are completely toast. There is absolutely nothing tying you to ChatGPT because ChatGPT doesn't matter, only what it produces.
Amazon was in a (similar) situation, but not quite, because they offered a unique experience. But I strongly believe that if Sears just kept their catalogue for another decade, Amazon would not exist.
