Completely understand the sentiment, but it doesn't apply here, because what's being generated are formulas!
Standardized 3-statement models in Excel are designed to be auditable, with or without AI, because (to only slightly simplify) every cell is either a blue input (which must come from standard exports of the company's accounting books, other auditable inventory/CRM/etc. data, or a visible hardcoded constant), or a black formula that cannot have hardcoded values, and must be simple.
If every buyer can audit, with tools like this, that the formulas match the verbal semantics of the model, there's even less incentive than there is now to fudge the formula level. (And with Wall Street conventions, there's nowhere to hide a prompt injection, because you're supposed to keep every formula to only a few characters, and use breakout "build" rows that can themselves be visually audited.)
And sure, you could conceivably use any AI tool to generate a plausible list of numbers at the input level, but that was equally easy, and equally dependent on context to be fraudulent or not, ever since that famous Excel 1990 elevator commercial: https://www.youtube.com/watch?v=kOO31qFmi9A&t=61s
At the end of the day, the difference between "they want to see this growth, let's fudge it" and "they want to see this growth, let's calculate the exact metrics we need to hit to make that happen, and be transparent about how that's feasible" has always been a matter of trust, not technology.
Tech like this means that people who want to do things the right way can do it as quickly as people who wanted to play loose with the numbers, and that's an equalizer that's on the right side of history.
