Yes - that is the right question :) We'll do a followup where we figure this out because I agree that it's relevant. I would guess 95% at most.
For example, if you administered a leetcode style examination to me, even at the easy level, I'd probably fail miserably compared to an AI.
However, I am a far more competent professional programmer than an AI.
Is accounting all just rote knowledge? Is there some degree of correctness that can be measured?
Will be interested to see what you come up with if you plan to put data behind your business model.
99% hampered with low-cognitive throughput tasks, where most of your business value is generated in the 1% of what you do.
It's possible that AI isn't close to replacing human efforts.
