Will difficulty rise so quickly that single GPU miner's like me will have no profit all?

I would certainly expect so.

A more interesting question is: "How long until the fastest and most efficient ASIC today are no longer profitable to run?
I'd guess less than 5 years.

5 year... yeah, no.

How many years did it take for CPUs to become unprofitable?

Once CPUs were unprofitable, how much longer did it take for the early GPUs to become unprofitable?

Now that GPUs are becoming unprofitable why would you think it would take more than 5 years for today's ASIC to become unprofitable?
