Indeed, Rich Sutton argued that we already have been through an exponential phase of self-improvement, we have been using computers to build better computers for decades, and have been using technology to improve our learning and cognition for a long time.
Piece this together with: 'Brain efficiency: Much more than you wanted to know' [1] which shows how our brains are incredibly efficient (near theoretical limits) at what they do, it's hard to think a bona fide intelligence singularity is anywhere likely. To quote Feynman, 'There is no miracle people'[2], and analogously 'There are no miracle beings' -- intelligence is built out of systems, and learning, and inference.
There's a possibility that the skills relevant to AI success are vastly different from our natural skills, such that although the human brain is highly efficient, it's efficient at the wrong things. That's clearly true in a few ways: we are not so good at arithmetic for example, a small CPU can literally be millions-billions times faster than a human at that. (that's addressed a little in the article as well) I wonder if AI could indeed be vastly better at something like computer programming, mathematics than we are. But there's no singularity (at most a Moore-like law will continue until AI intelligence saturates at a different skillset than our own).

- NineStarPoint 5y agoMore importantly than what it’s capable of, the human brain is ultimately limited by our inability to increase its complexity. A human brain takes approximately 20 watts of power and uses 3 pounds of material to do its calculations. Even with less efficiency, we can make machines much larger than that. If AGI is possible at all, it should be possible to make an AGI that can have thoughts many times more complex than the human brain can. (Such a large machine might not have the reaction speed of a human, but the evolutionary pressures that required us to be able to quickly change our train of thought in response to danger aren’t a limiting factor to any designed intelligence)
