Two chairs
Ray Kurzweil says computing's exponential growth will produce human-level AI by 2029 and merge humans with machines by 2045. If the curve holds, that's arithmetic. If it doesn't, it's a chart that flatters itself.
In 2005, Ray Kurzweil's The Singularity Is Near predicted human-level AI by 2029 and a merging of human and machine intelligence by 2045, driven by exponential gains in computing. His 2024 sequel, The Singularity Is Nearer, kept both dates unchanged. Does the curve hold, or is it a chart that flatters itself?
What's checkable: Kurzweil published these dates in 2005 and kept them in 2024. What isn't: whether an extrapolated curve is a law or a story that has held so far. Both chairs agree computing grew exponentially; they disagree on what that guarantees.
