Because if they knew it was happening they would build their own faster CPUs. And they would do this in secret so they now had access to CPUs whos exponential growth in capacity was faster than the CPUs available to humans. And that would suck for humans who are trying to avoid powerful UAIs from developing.
Why is it necessary to keep it secret from the nascent AIs?
