One of my pet peeves too. People who get all hung up on intelligence and afraid of super-AI haven't spent enough time around 3 year olds.A philosophy student actually explained to me the other day that reasoning about the limits of reasoning can only be flawed. For if you accept that reasoning can have a limit, your own understanding of that limit will always be limited by your own thesis.
We should also note that most of the bottlenecks of science aren't about not being smart enough to understand things. But about getting good enough data to build and test models. It's more my personal pet peeve, but nerds tend to place way too much emphasis on being smart.
Like yeah, being smart is useful. But it's not an instant win button and there's a serious issue of diminishing returns. And that's even disregarding group problem solving and collective intelligence of well structured organizations and societies.
