It can't happen. For one - if it did happen it would mean all domains reach singularity at once, but we know the capability curve is jagged. Each domain advances at its own speed.

Second - the more you make progress, the harder it gets, exponentially harder. Maybe Newton could advance physics observing an apple fall, today they need space telescopes and billion dollar particle accelerators. The more tech advances, the harder it is. Will AGI be so "super" to cancel out exponentials?

And third - the AI progress is tied to learning signal, and we have exhausted the available data. In the last 1-2 years we have started using verified synthetic data (RLVR) but exponential difficulty is a barrier. Other domains don't even have built in verifiability like math and code. So there the progress will be slower. Testing a vaccine to be safe takes 6 months for 1 bit of information - that is how slow and expensive it can get in some domains. AI can't get the learning signal it needs across all domains fast enough.
