Why tho? You used AI to make some software, but did you use AI to achieve rapid revenue acceleration?

That you used AI to build software seems tangential to whether it can increase revenues. Over the years, we've seen many technologies that didn't deliver on promises of rapidly increasing revenues despite being useful for creating software (cough OOP cough), so this new one failing to live up to expectations isn't surprising. Actually given the history of technologies that over promise and under deliver on massive hype, disappointment should be the null hypothesis.
