When it stops being profitable to continue scaling transistors. The reason we scale is because it makes chips cheaper, faster, just plain better, meaning Intel and AMD (and others) can sell it for lots of money. If scaling no longer achieves that goal, you'll see it end in a heartbeat (just like you saw clock speed ramping come to a halt once it wasn't selling like it used to).
