It's very easy to claim some software would've taken you months to make, but this is ridiculous. Estimating project duration is well known to be impossible in this field. A few years ago you'd get laughed out the room for making such predictions.

Respectfully, what are you doing here?
Yeah sure, the Apple dream. But supposing AI did in fact make you this legendary 100x developer, so it would to everyone else including those with significantly more resources. You'd still be run out of the market by those with bigger budgets or more marketing, and end up penniless all the same.
I would strongly recommend you not put all your proverbial eggs in this basket.
