If the rate of improvement continues at the current pace - which is GPT 1 to 2 to 3 to 4 in the last five years - we are just one or two improvements away from a full blown AGI/superintelligence/singularity/etc. At that point, a superior user interface is probably the least interesting (or scary) thing that would happen.
I personally doubt GPT-5 will be as much of an improvement over GPT-4 as GPT-4 was over GPT-3, but that's fine, I can wait until GPT-6 or 7.
