REX is not AI
That’s a choice.
Not a gap.
REx was built to model fifteen years of reward decisions with precision and auditability. Every number traceable to the employee, the parameter, the policy behind it.
AI cannot give you that. REx can.
But that boundary is about your numbers.
For mine, I draw it differently.
my second pair of eyes
Where AI earns its place.
Before I touch anything, AI has already mapped where something might quietly break, three steps down. And when I do make a change, it logs exactly what shifted, why it shifted, and where the change ripples.
I miss the typo on row 847. AI doesn’t. And AI goes further than typos and checksums. It scans every number and every pattern against the complete REx context. Model validation. Faster. Broader. And without ever losing its fresh eye.
It turns a set of numbers into a narrative: not just what changed, but why it changed and what could amplify the change. It also catches the patterns that don’t surface in the charts.
AI saves me from myself.
Fast. Without ever sighing.
I challenge every answer.
I confirm what holds,
correct what does not
occasionally
It is also, occasionally,
completely wrong.
Not always obviously. Sometimes it misses by a lot. Sometimes just slightly — and the slight misses are the ones that cost you.
So I challenge every answer. I confirm what holds, correct what does not, and add the context it overlooked.
That push back is not optional. AI needs direction. But every push back lands. And stacks.
Should the REx calculation engine move to Python? Should REX become a SaaS product? Should a simulation return a probability cloud instead of a single outcome?
AI helps me think through the scope, the implications, the trade-offs. Rigorously, without flattering me.
It is the thinking partner I do not otherwise have as a solo practice.
The fifteen-year view I build for you runs without AI.
For Falco, I made a different choice.
And then there is falco
