This is an assumption, how would you know if you have alignment? AGI could appear to align, just as a psychopath appears studies and emulates well behaved people. Imagine that at a scale we can't possibly understand. We don't really know how any of these emergent behaviors really work, we just throw more data and compute and fine tunings at it, bake it, and then see.
We would know because we have AI helping us at every step of the way. Our own abilities, to do everything including gauge alignment, are enhanced by AI.
