I would stop that kind of evolution, as it can be catastrophic, but I know that humanity is not able to stop itself from evolving further.
An 18 year old will have been training for ~160,000 hours on a volume of raw data that is probably far beyond our ability to currently store let alone train an AI with.
As far as training for a specific task, all that training on other matters kicks in to help the human learn or accomplish a “novel” task more rapidly, for example, knowing how to read and interpret the instructions for that task, knowing how to move your appendages and the expected consequences of your physical interactions with a material object. You’re certainly not taking a fetus with a blank slate and getting it to accomplish much at all.
If you are also saying AIs will be a more intelligent species, able to adapt better on Earth than humans, that requires extraordinary evidence. A human could solve complex problems no other species it machine can solve on nothing more than a handful of rice for a week. Where is the similar scale species/machine?
And even then for proper agi it would need to close the loop after inducing an hypothesis with testing.
Meatbags are going to be useful for a while still.
It can translate code from one language to another. Code that it has never seen before. Or between natural language and programming language.
It's certainly not perfect but it is reasoning all right
