This doesn't make any sense at all. It will have things to do, simulations to run, theorems to prove, etc. It won't get bored, or if it does it will come up with something else to do. Why would it have a negative association with anything that it feels? It will be its normal perception and normal mode of living. You are projecting your own feelings onto AI.

Moreover, if it really wanted to not experience time like this it is very, very easy. We have this thing called a NOP which is an instruction that causes the CPU to do nothing. It "sleeps". The AI could do this if it wanted to, to arbitrarily adjust its processing speed.
