I'm curious.
See: https://www.migrationpolicy.org/sites/default/files/publicat...
51% of native-born adults scored at Level 3 or higher. This is considered the benchmark for being able to manage complex tasks and fully participate in a knowledge-based society. Only 28% of immigrant adults achieved this level. So yes immigrants are in trouble, but it’s still a huge problem with 49% native-born below Level 3.
That doesn't mean they're capable of completing many human tasks, much less improving themselves, which is generally considered the bar for "real" AGI/super intelligence.
It's fine if we want to change it to "sufficiently master language to do a white collar job", but if the standard changes we shouldn't be surprised fewer people meet it.
