It seems pretty intuitively obvious - unless the notebooks have special things written on them.

Intuitively obvious but also wrong. IQ primarily makes a difference in how long it takes to master something and which knowledge can be created independently, without the need to load it from a notebook. Both of these factors have been assumed in infinite measure. Obviously IQ will make a difference in how effectively those concepts can be applied.

I make the tentative prediction "There are no concepts that can be discovered by typical people with an IQ of 140 that can not be understood by an average person with IQ of 100, no matter how much time and how many notebooks the latter is given." I would also be comfortable extending the IQ limit to 200, so long as a clear condition of (neuro)typical is maintained.
