For comparison, the average person can't print Hello World in python. Your average programmer (probably) can.

It's surprisingly simple to be above average in most tasks. Which people often confuse with having expertise. It's probably pretty easy to get into the 80th percentile of most subjects. That won't make you the 80th percentile of people that do the thing, but most people don't. I'd wager 80th percentile is still amateur.

But only the limited number of tasks per human.

Even if it performs just better than untrained human but on any task this will be superhuman level. As no human can do it.

The G in AGI stands for "general", not for "superhuman". An intelligence that can't learn to perform information processing and decision-making tasks people routinely do does not seem very general to me.

Here is the big question: should it be equal or better then every single person? If we assume that every healthy person is 'generally intelligent' then probably this is a benchmark. Because not every person can do the tasks that other persons do routinely. Probably we shouldn't demand it from AGI either. At least not from a single model. But it makes sense to request that specialized model can be created (or trained, fine tuned) for every task humans can do.
