In contradistinction to this orthodoxy, I find the following five heresies to have more evidence to support them.
Intelligence is not a single dimension, so “smarter than humans” is a meaningless concept.
Humans do not have general purpose minds, and neither will AIs.
Emulation of human thinking in other media will be constrained by cost.
Dimensions of intelligence are not infinite.
Intelligences are only one factor in progress.
