What Are the Time Scales for a I?

We don't know much about the details of aayet. It's like worrying about cars in 17 hundredyoudon't worry about nuclear bombs in 15 hundred red. So i more want to say, how many doubling times will it be till something happens? And so i'd say, within our current regime, it'll be half a century to sever centuries until we get some form of ai - either ms or other sort. But then when that happens, within a few years, you can have vast amounts of change, which would also include cronics. Right?
